PROSPECTUS

Proxy Statement/Prospectus

MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

Dear Shareholder:

On September 9, 2024, NBT Bancorp Inc., a Delaware corporation (“NBT”), NBT’s wholly-owned subsidiary, NBT Bank, National Association (“NBT Bank”), Evans Bancorp, Inc., a New York corporation (“Evans”) and Evans’s wholly-owned subsidiary, Evans Bank, National Association (“Evans Bank”) entered into an Agreement and Plan of Merger (the “merger agreement”) pursuant to which (i) Evans will merge with and into NBT, with NBT as the surviving entity, and (ii) Evans Bank will merge with and into NBT Bank, with NBT Bank as the surviving entity.

Evans is holding a special meeting for its shareholders to vote on the merger agreement. The special meeting of Evans shareholders will be held virtually on December 20, 2024, at 11:00 a.m., Eastern time. At the special meeting of Evans shareholders, Evans shareholders will be asked to consider and vote on (i) a proposal to approve the merger agreement (the “merger proposal”), (ii) a proposal to approve, on an advisory (non-binding) basis, specified compensation that may become payable to the named executive officers of Evans in connection with the merger (the “compensation proposal”), and (iii) a proposal to approve one or more adjournments of the Evans special meeting, if necessary or appropriate, to permit further solicitation of proxies if there are insufficient votes at the time of the special meeting, or at an adjournment or postponement of that meeting, to approve the merger proposal (the “adjournment proposal”). Approval of the merger proposal requires the affirmative vote of two-thirds of all outstanding shares entitled to vote on the proposal. Approval of each of the compensation proposal and the adjournment proposal requires the affirmative vote of a majority of the votes cast on such proposal. The Evans Board of Directors recommends unanimously that all Evans shareholders vote “FOR” the merger proposal, “FOR” the compensation proposal and “FOR” the adjournment proposal.

If the merger is completed, Evans shareholders will receive 0.91 shares of NBT common stock for each share of Evans common stock they own on the effective date of the merger. Evans shareholders will also receive cash in lieu of any fractional shares they would have otherwise received in the merger.

NBT common stock is listed on the NASDAQ Stock Market under the symbol “NBTB.” Evans common stock is listed on the NYSE American LLC under the symbol “EVBN.” On September 9, 2024, which was the last trading day preceding the public announcement of the proposed merger, the closing price of NBT common stock was $45.95 per share, which after giving effect to the exchange ratio, has an implied value of $41.81 per share. On November 1, 2024, which was the most recent practicable trading day before the printing of this proxy statement/prospectus, the closing price of NBT common stock was $44.56 per share, which after giving effect to the exchange ratio, has an implied value of approximately $40.55 per share. The market price of NBT common stock will fluctuate between now and the closing of the merger. We urge you to obtain current market quotations for NBT common stock before you vote.

Your vote is important regardless of the number of shares you own. Whether or not you plan to attend the special meeting, please take the time to vote by internet, by telephone, or by completing and mailing the enclosed proxy card as soon as possible to make sure your shares are represented at the special meeting. If you submit a properly signed proxy card without indicating how you want to vote, your proxy will be counted as a vote “FOR” each of the proposals being voted on at the special meeting. The failure to vote by submitting your proxy or attending the special meeting and voting electronically during the meeting will have the same effect as a vote against the merger proposal.

This document serves as the proxy statement for the special meeting of Evans and the prospectus for the shares of NBT common stock to be issued in connection with the merger, and describes the Evans special meeting, the merger, the documents related to the merger and other related matters. We encourage you to read this proxy statement/prospectus in its entirety, including the documents attached as annexes and the section titled “Risk Factors” beginning on page 15.

Thank you for your cooperation and continued support.

Sincerely,

Lee C. Wortham

Chairman of the Board of Directors

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE EVANS SPECIAL MEETING

The following questions and answers are intended to address briefly some commonly asked questions regarding the merger and the Evans special meeting. These questions and answers may not address all questions that may be important to you as a shareholder. To better understand these matters, and for a description of the legal terms governing the merger, you should carefully read this entire proxy statement/prospectus, including the annexes, as well as the documents that have been incorporated by reference into this proxy statement/prospectus.

Q:	Why am I receiving this proxy statement/prospectus?

The respective boards of directors of NBT Bancorp Inc. (“NBT”), NBT Bank, National Association, NBT’s subsidiary bank (“NBT Bank”), Evans Bancorp, Inc. (“Evans”) and Evans Bank, National Association, Evans’s subsidiary bank (“Evans Bank”), each approved a merger agreement, which is described in this proxy statement/prospectus, among NBT, NBT Bank, Evans and Evans Bank pursuant to which (i) Evans will merge with and into NBT, with NBT as the surviving entity and (ii) Evans Bank will merge with and into NBT Bank, with NBT Bank as the surviving entity. A copy of the merger agreement is attached to this proxy statement/prospectus as Annex A. In order to complete the merger, Evans shareholders must vote to approve the merger agreement. Evans will hold a virtual special meeting of shareholders to obtain this approval. This proxy statement/prospectus contains important information about the merger, the merger agreement, the special meeting of Evans shareholders and other related matters, and you should read it carefully. The enclosed voting materials for the Evans special meeting allow you to vote your shares of common stock without attending the special meeting online.

We are delivering this proxy statement/prospectus to you as both a proxy statement of Evans and a prospectus of NBT. It is a proxy statement because the Evans Board of Directors is soliciting proxies from Evans shareholders to vote on the approval of the merger proposal and the compensation proposal (each as defined below) at the Evans special meeting of shareholders and adjournments of the special meeting, if necessary, for the purpose of soliciting additional proxies in favor of the merger proposal. Your proxy will be used at the Evans special meeting or at any adjournment or postponement of the special meeting. It is also a prospectus because NBT will issue NBT common stock to Evans shareholders as consideration in the merger, and this prospectus contains information about the NBT common stock.

Q:	What will happen in the merger?

In the proposed merger, (i) Evans will merge with and into NBT, with NBT as the surviving entity, and (ii) Evans Bank will merge with and into NBT Bank, with NBT Bank as the surviving entity. Each share of Evans common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.91 shares of NBT common stock.

Q:	What are the proposals on which I am being asked to vote?

You are being asked to vote on the following proposals: (i) to approve the merger agreement (the “merger proposal”), (ii) to approve, on an advisory (non-binding) basis, specified compensation that may become payable to the named executive officers of Evans in connection with the merger (the “compensation proposal”) and (iii) to approve one or more adjournments or postponements of the special meeting, if necessary, for the purpose of soliciting additional proxies in favor of the proposal to approve the merger agreement (the “adjournment proposal”).

Q:	What will I receive in the merger?

If the merger proposal is approved and the merger is subsequently completed, Evans shareholders will be entitled to receive 0.91 shares of NBT common stock for each outstanding share of Evans common stock held at the effective time of the merger and cash in lieu of fractional shares as described below.

The value of the merger consideration is dependent upon the value of NBT common stock and therefore will fluctuate with the market price of NBT common stock. Accordingly, any change in the price of NBT common stock prior to the merger will affect the market value of the merger consideration that Evans shareholders may receive upon the closing of the merger.

TABLE OF CONTENTS

Q:	What will happen to shares of NBT common stock in the merger?

Each share of NBT common stock outstanding held by NBT shareholders immediately before the merger will continue to represent one share of NBT common stock after the effective time of the merger. Accordingly, NBT shareholders will receive no consideration in the merger and the merger will not change the number of shares an NBT shareholder currently owns.

Q:	Will I receive any fractional shares of NBT common stock as part of the merger consideration?

No. NBT will not issue any fractional shares of NBT common stock in the merger. Instead, NBT will pay Evans shareholders the cash value of a fractional share (without interest) in an amount determined by multiplying the fractional share interest to which such shareholder would otherwise be entitled by the average of the daily closing sales prices of one share of NBT common stock as reported on the NASDAQ Stock Market, LLC (“NASDAQ”) for the five consecutive trading days ending on the third business day immediately prior to the closing date of the merger, rounded to the nearest whole cent.

Q:	Is there a termination fee potentially payable under the merger agreement?

A:	Yes. Under certain circumstances, Evans may be required to pay NBT a termination fee if the merger agreement is terminated. See “The Merger Agreement—Termination Fee” on page 71 for more information.

Q:	As an Evans shareholder, why am I being asked to cast a non-binding advisory vote to approve the compensation that may become payable to Evans’s named executive officers in connection with the merger?

A:	The SEC’s rules require Evans to seek a non-binding advisory vote with respect to certain “golden parachute” compensation that may become payable to Evans’s named executive officers in connection with the merger.

Q:	What will happen if Evans shareholders do not approve the compensation that may become payable to Evans’s named executive officers in connection with the merger?

The vote with respect to the “golden parachute” compensation is an advisory vote and will not be binding on Evans or NBT. Approval of the compensation that may become payable to Evans’s named executive officers is not a condition to completion of the merger. Therefore, if the merger proposal is approved by Evans’s shareholders and the merger is subsequently completed, the compensation will still be paid to Evans’s named executive officers, whether or not Evans’s shareholders approve the compensation at the Evans special meeting.

Q:	What are the material U.S. federal income tax consequences of the merger to U.S. holders of shares of Evans common stock?

The merger is intended to qualify for U.S. federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and it is a condition to our respective obligations to complete the merger that each of Evans and NBT receives a legal opinion to the effect that the merger will so qualify. Assuming the merger so qualifies, Evans shareholders generally will not recognize any gain or loss for U.S. federal income tax purposes on the exchange of their Evans common stock for NBT common stock in the merger, except that such holders will recognize gain or loss to the extent such holders receive cash in lieu of any fractional share of NBT common stock that an Evans shareholder would otherwise be entitled to receive. See “PROPOSAL 1—The Merger—Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 53.

Q:	Will I be able to trade the shares of NBT common stock that I receive in the merger?

You may freely trade the shares of NBT common stock issued in the merger unless you are an “affiliate” of NBT as defined by Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”). Affiliates consist of individuals or entities that control, are controlled by, or are under common control with NBT and include executive officers and directors and may include significant shareholders of NBT.

TABLE OF CONTENTS

Q:	What are the conditions to completion of the merger?

The obligations of NBT and Evans to complete the merger are subject to the satisfaction or waiver of certain closing conditions contained in the merger agreement, including the receipt of required regulatory approvals and/or waivers, receipt of tax opinions and the approval of the merger proposal by the shareholders of Evans.

Q:	When do you expect the merger to be completed?

We will complete the merger when all of the conditions to completion contained in the merger agreement are satisfied or waived, including obtaining required regulatory approvals and the approval of the merger proposal by Evans’s shareholders at Evans’s special meeting. While we expect the merger to be completed in the second quarter of 2025, because fulfillment of some of the conditions to completion of the merger is not entirely within our control, we cannot assure you of the actual timing.

Q:	What Evans shareholder approval is required to complete the merger?

A:	The merger cannot be completed unless Evans receives the affirmative vote of two-thirds of all outstanding shares entitled to vote on the merger proposal.

Q:	Are there any Evans shareholders already committed to voting in favor of the merger proposal?

Yes. Each of the directors and executive officers of Evans, solely in such director’s or officer’s capacity as a shareholder of Evans, has entered into a voting agreement with NBT requiring each of them to vote all shares of Evans common stock owned by such director or executive officer in favor of the merger proposal. As of the record date, these directors and executive officers held 263,149 shares of Evans common stock, which represented approximately 4.7% of the outstanding shares of Evans common stock.

Q:	When and where is the Evans special meeting?

A:	The special meeting of shareholders of Evans will be held virtually at meetnow.global/M4KLWH9 on December 20, 2024, at 11:00 a.m., Eastern time.

Q:	What will happen at the Evans special meeting?

At the Evans special meeting, Evans shareholders will consider and vote on the merger proposal and the compensation proposal. If, at the time of the special meeting, there are insufficient votes for the shareholders to approve the merger proposal, you may be asked to consider and vote on the adjournment proposal.

Q:	Who is entitled to vote at the Evans special meeting?

All holders of Evans common stock who held shares at the close of business on November 1, 2024, which is the record date for the special meeting of Evans shareholders, are entitled to receive notice of and to vote at the Evans special meeting. Each holder of Evans common stock is entitled to one vote for each share of Evans common stock owned as of the record date.

Q:	What constitutes a quorum for the Evans special meeting?

A:	The quorum requirement for the special meeting is the presence at the virtual meeting or by proxy of the holders of a majority of the total number of shares of Evans common stock entitled to vote. Abstentions will be counted for purposes of determining whether a quorum is present.

Q:	How does the Evans Board of Directors recommend I vote?

A:	After careful consideration, the Evans Board of Directors unanimously recommends that all shareholders vote “FOR” the merger proposal, “FOR” the compensation proposal and “FOR” the adjournment proposal, if necessary.

TABLE OF CONTENTS

Q:	Are there any risks that I should consider in deciding whether to vote for approval of the merger proposal?

Yes. You should read and carefully consider the risk factors set forth in the section in this proxy statement/prospectus entitled “Risk Factors” beginning on page 15 as well as the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed in the section of this proxy statement/prospectus titled “Information Regarding Forward-Looking Statements” on page 23.

Q:	What do I need to do now?

You should carefully read and consider the information contained in or incorporated by reference into this proxy statement/prospectus, including its annexes. It contains important information about the merger, the merger agreement, NBT and Evans. After you have read and considered this information, you should vote by internet, by telephone, or by completing and mailing your proxy card in the enclosed postage-paid return envelope as soon as possible so that your shares will be represented and voted at the Evans special meeting.

Q:	How may I vote my shares for the special meeting proposals presented in this proxy statement/prospectus?

You may vote by internet, by telephone, by completing and mailing the proxy card in the enclosed postage-paid envelope, or by casting your vote online at the virtual meeting. Information and applicable deadlines for voting through the internet or by telephone are set forth in the enclosed proxy card instructions. You may revoke your proxy at any time prior to its exercise, and you may attend the special meeting and vote, even if you have previously returned your proxy card or voted via the internet or by telephone.

Q:	Can I attend the virtual special meeting and vote my shares electronically during the meeting?

Yes. Although the Evans Board of Directors requests that you return the proxy card accompanying this proxy statement/prospectus, all Evans shareholders, including shareholders of record and shareholders who hold their shares in “street name” through banks, brokers, trustees or other nominees, are invited to attend the virtual special meeting online. Shareholders of record on November 1, 2024 can vote electronically during the special meeting.

Shareholders who hold their shares through an intermediary, such as a bank or broker, must register in advance to attend and vote online at the special meeting. To register, shareholders must submit a legal proxy reflecting their Evans common stock holdings along with their name and email address to Computershare at legalproxy@computershare.com. Requests for registration must be labeled as “Legal Proxy” and be received no later than 5:00 p.m., Eastern Time, on December 17, 2024. Shareholders will receive a confirmation email with a control number from Computershare regarding their registration.

Q:	How will my shares be represented at the Evans special meeting?

At the Evans special meeting, the individuals named in your proxy card will vote your shares in the manner you requested if you properly signed and submitted your proxy. If you sign your proxy card and return it without indicating how you would like to vote your shares, your proxy will be voted: (1) “FOR” the merger proposal, (2) “FOR” the compensation proposal and (3) “FOR” the adjournment proposal.

Q:	If my shares are held in “street name” by my broker, bank, trustee or other nominee, will my broker, bank, trustee or other nominee automatically vote my shares for me?

No. Your broker, bank, trustee or other nominee will not vote your shares unless you provide instructions to your broker, bank or other nominee on how to vote. You should instruct your broker, bank or other nominee to vote your shares by following the instructions provided by the broker, bank or nominee with this proxy statement/prospectus.

Q:	What if I fail to submit my proxy card or to instruct my broker, bank, trustee or other nominee?

If you fail to properly submit your proxy card, and you do not attend the special meeting and vote your shares online during the virtual meeting, your shares will not be voted, which will have the same effect as a vote against the merger proposal. If a quorum is present at the special meeting, this will not affect the outcome of the compensation proposal or adjournment proposal.

TABLE OF CONTENTS

Q:	What if I abstain from voting on a matter?

For purposes of the special meeting, an abstention occurs when a shareholder attends the special meeting but abstains from voting. Abstentions will be counted for purposes of determining whether a quorum is present. Abstentions will have the same effect as a vote against the merger proposal and no effect on the outcome of the compensation proposal or adjournment proposal.

Q:	What is a “broker non-vote”?

Banks, brokers, trustees and other nominees who hold shares in street name for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, banks, brokers, trustees and other nominees are not allowed to exercise their voting discretion with respect to the approval of matters determined to be “non-routine” without specific instructions from the beneficial owner.

A broker non-vote occurs when a bank, broker, trustee or other nominee is not permitted to vote on a “non-routine” matter without instructions from the beneficial owner of the shares and the beneficial owner fails to provide the bank, broker, trustee or other nominee with such instructions. Broker non-votes only count toward a quorum if at least one proposal is presented with respect to which the bank, broker, trustee or other nominee has discretionary authority. It is expected that all proposals to be voted on at the Evans special meeting will be “non-routine” matters, and, as such, broker non-votes, if any, will not be counted as present and entitled to vote for purposes of determining a quorum at the Evans special meeting. If your bank, broker, trustee or other nominee holds your shares of Evans common stock in “street name,” such entity will vote your shares of Evans common stock only if you provide instructions on how to vote by complying with the instructions provided to you by your bank, broker, trustee or other nominee with this proxy statement/prospectus.

If you do not provide instructions on how to vote, your bank, broker, trustee or other nominee may not vote your shares on the merger proposal, the compensation proposal or the adjournment proposal, which broker non-votes, if any, will have the same effect as a vote against the merger proposal and no effect on the outcome of the compensation proposal or adjournment proposal.

Q:	Can I change my vote after I have submitted my proxy?

A:	Yes. There are three ways you can change your vote at any time after you have submitted your proxy and before your proxy is voted at the special meeting:

•	you may deliver a written notice bearing a date later than the date of your proxy card to Evans’s Secretary at the address listed below, stating that you revoke your proxy;

•	you may submit a new signed proxy card bearing a later date (if you submitted your proxy by internet or by telephone, you can vote again by internet or telephone); or

•	you may attend the virtual special meeting and vote online during the meeting, although attendance at the special meeting will not, by itself, revoke a proxy.

You should send any notice of revocation to:

Evans Bancorp, Inc.

6460 Main Street

Williamsville, New York 14221

Attention: Michelle A. Baumgarden

Corporate Secretary

Purpose of the Special Meeting (Page 27)

At the special meeting, you will be asked to vote on the following:

1.	the merger proposal;

2.	the compensation proposal; and

3.	the adjournment proposal, if necessary.

Recommendation of Evans Board of Directors (Page 27)

The Evans Board of Directors unanimously recommends that you vote “FOR” the merger proposal, “FOR” the compensation proposal and “FOR” the adjournment proposal.

Record Date; Outstanding Shares; Shares Entitled to Vote (Page 27)

Only holders of record of Evans common stock at the close of business on the record date of November 1, 2024 are entitled to notice of and to vote at the special meeting. As of the record date, there were 5,541,064 shares of Evans common stock outstanding, held of record by approximately 960 shareholders.

TABLE OF CONTENTS

Quorum; Vote Required (Page 27)

A quorum of Evans shareholders is necessary to hold a valid meeting. If the holders of at least a majority of the total number of shares of Evans common stock entitled to vote are present at the virtual special meeting or represented by proxy at the special meeting, a quorum will exist. Abstentions will be counted for purposes of determining whether a quorum is present.

Assuming a quorum is present at the Evans special meeting, approval of the merger proposal requires the affirmative vote of two-thirds of all outstanding shares entitled to vote on the proposal, and approval of each of the compensation proposal and the adjournment proposal requires the affirmative vote of a majority of the votes cast on such proposal.

Abstentions and broker non-votes will have the same effect as a vote against the merger proposal and no effect on the compensation proposal or the adjournment proposal.

Share Ownership of Management; Voting Agreements (Page 27)

As of the record date, the directors and executive officers of Evans collectively held 263,149 shares of Evans common stock, which represented approximately 4.7% of the outstanding shares of Evans common stock.

Each of the directors and executive officers of Evans have entered into a voting agreement with NBT, requiring each of them to vote all shares of Evans common stock beneficially owned by such person in favor of approval of the merger agreement.

The Merger and the Merger Agreement

The terms and conditions of the merger are contained in the merger agreement, a copy of which is attached as Annex A to this proxy statement/prospectus. You are encouraged to read the merger agreement carefully, and in its entirety, as it is the primary legal document that governs the proposed merger.

Pursuant to the terms and subject to the conditions set forth in the merger agreement, at the effective time of the merger, Evans will merge with and into NBT, with NBT as the surviving entity. Immediately thereafter, Evans Bank will merge with and into NBT Bank, with NBT Bank as the surviving bank (the “bank merger”). Following the merger, Evans common stock will be delisted from the NYSE American LLC (“NYSE”), will be deregistered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and will cease to be publicly traded.

Structure of the Merger (Page 59)

In the proposed merger, (i) Evans will merge with and into NBT, with NBT as the surviving entity, and (ii) Evans Bank will merge with and into NBT Bank, with NBT Bank as the surviving entity. Shares of NBT will continue to trade on NASDAQ with the NASDAQ trading symbol “NBTB.” Upon completion of the merger, the separate existences of Evans and Evans Bank will terminate.

Consideration to be Received in the Merger (Page 60)

Upon completion of the merger, each outstanding share of Evans common stock will be converted into the right to receive 0.91 shares of NBT common stock. No fractional shares of NBT common stock will be issued to any holder of Evans common stock upon completion of the merger. For each fractional share that would otherwise be issued, NBT will pay each shareholder cash (without interest) in an amount determined by multiplying the fractional share interest to which such shareholder would otherwise be entitled by the average of the closing sales prices of one share of NBT common stock on NASDAQ for the five trading days ending on the third business day immediately prior to the closing date, rounded to the nearest whole cent.

Treatment of Equity Awards (Page 60)

Stock Options. All unvested stock option grants shall vest immediately prior to the effective time so that all options outstanding at the effective time will automatically convert into the right to receive a lump sum cash payment equal to (i) the number of shares of Evans stock subject to such option, multiplied by (ii) the amount by which the per share consideration exceeds the per share exercise price of such option, less applicable taxes and other withholdings and without interest.

TABLE OF CONTENTS

Restricted Stock Awards. Any vesting restrictions on each restricted share of Evans common stock subject to a substantial risk of forfeiture outstanding immediately prior to the effective time of the merger will automatically lapse and all vested restricted stock awards will be exchanged for the merger consideration and will be treated as issued and outstanding shares of Evans common stock.

Performance-Based Restricted Stock Units. Each award of performance-based restricted stock units with respect to Evans common stock outstanding immediately prior to the effective time of the merger will become vested as to the number of shares that would vest based on the assumed achievement of the performance goals at the greater of the target level or actual achievement level (measured at the date of the merger) and all vested performance-based restricted stock units will be exchanged for the merger consideration.

Time-Based Restricted Stock Units. Each award of time-based restricted stock units with respect to Evans common stock outstanding immediately prior to the effective time of the merger will become vested as of the effective time and all vested restricted stock units will be exchanged for the merger consideration and will be treated as issued and outstanding shares of Evans common stock for purposes of the merger agreement.

Opinion of Piper Sandler & Co., Financial Advisor to Evans (Page 37)

Piper Sandler & Co. (“Piper Sandler”) acted as financial advisor to Evans in connection with the proposed merger and participated in certain of the negotiations leading to the execution of the merger agreement. As part of its engagement, representatives of Piper Sandler attended the meeting of the Evans Board of Directors held on September 9, 2024, at which the Evans Board of Directors evaluated the proposed merger and the merger agreement. At this meeting, Piper Sandler reviewed the financial aspects of the proposed merger and provided its opinion that, as of such date, the merger consideration was fair, from a financial point of view, to the shareholders of Evans. The full text of Piper Sandler’s opinion is attached as Annex B to this proxy statement/prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler in rendering its opinion. Holders of Evans common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Piper Sandler’s opinion was directed to the Evans Board of Directors in connection with its consideration of the merger and the merger agreement and does not constitute a recommendation to any shareholder of Evans as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger or the merger agreement. Piper Sandler’s opinion was directed only to the fairness, from a financial point of view, of the exchange ratio to the holders of Evans common stock and did not address the underlying business decision of Evans to engage in the merger, the form or structure of the merger or any other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative transactions or business strategies that might exist for Evans or the effect of any other transaction in which Evans might engage. See the section of this proxy statement/prospectus entitled “PROPOSAL 1—The Merger—Opinion of Piper Sandler & Co., Financial Advisor to Evans” beginning on page 37 for more information relating to Piper Sandler’s opinion.

Interests of Certain Evans Directors and Executive Officers in the Merger (Page 48)

In considering the information contained in this proxy statement/prospectus, you should be aware that Evans’s directors and executive officers have interests in the merger that are different from, or in addition to, the interests of Evans shareholders generally. The Evans Board of Directors was aware of these interests and considered them, among other things, in approving the merger. These interests include, among other things:

•

accelerated vesting of stock option grants immediately prior to the effective time with all vested options outstanding at the effective time automatically converted into the right to receive a lump sum cash payment equal to (i) the number of shares of Evans stock subject to such option, multiplied by (ii) the amount by which the per share consideration exceeds the per share exercise price of such option, less applicable taxes and other withholdings;

•	accelerated vesting of outstanding restricted stock awards immediately prior to the effective time, and all vested restricted stock awards will be exchanged for the merger consideration and will be treated as issued and outstanding shares of Evans common stock for purposes of the merger agreement;

TABLE OF CONTENTS

•

accelerated vesting of outstanding performance-based restricted stock units based on the assumed achievement of the performance goals at the greater of the target level or actual achievement level (measured at the date of the effective time) and all vested performance-based restricted stock units will be exchanged for the merger consideration;

•

accelerated vesting of outstanding time-based restricted stock units immediately prior to the effective time, and all vested restricted stock units will be exchanged for the merger consideration and will be treated as issued and outstanding shares of Evans common stock for purposes of the merger agreement;

•	increased contributions to participating executives under the Executive Incentive Retirement Plan;

•	pro-rated 2025 annual bonus, in connection with or prior to the effective time of the merger;

•

severance payments and continued medical, health and life insurance benefits for a period of time (or a cash lump sum payment if such coverage cannot be provided) under current employment or change in control agreements in the event of involuntary termination without cause or termination for good reason in connection with the merger, for each of David J. Nasca, President and Chief Executive Officer of Evans and Evans Bank; John B. Connerton, Treasurer of Evans and Executive Vice President and Chief Financial Officer of Evans Bank; Kenneth D. Pawlak, Executive Vice President and Chief Growth Officer of Evans Bank; and five other officers of Evans;

•

certain executives and officers may receive accelerated vesting of restricted stock awards, restricted stock units (time-based and performance-based) and/or early payment of cash bonuses in calendar year 2024 in order to mitigate the impact of any contractual 280G cutback provision contained in any of their applicable agreements with Evans and/or Evans Bank if such cutbacks are projected to impact such executive;

•	continued indemnification and liability insurance coverage by NBT after the merger for acts or omissions occurring before the merger; and

•

NBT and NBT Bank will each appoint David J. Nasca to its board of directors following the closing of the merger (or, in the event of his unavailability, such other person as mutually agreed upon by NBT, NBT Bank, Evans, and Evans Bank), with related compensation for such services in the event that such individual is not otherwise concurrently employed by NBT or NBT Bank.

See the section of this proxy statement/prospectus entitled “PROPOSAL 1—The Merger—Interests of Evans’s Directors and Executive Officers in the Merger” beginning on page 48 for a discussion of these interests.

Boards of Directors of NBT and NBT Bank After the Merger (Page 59)

At the effective time of the merger, each of NBT and NBT Bank will appoint David J. Nasca (or, in the event of his unavailability, such other person as mutually agreed upon by Evans and NBT) to serve as a member of their respective boards of directors; provided, however, that if the effective time occurs between the date of NBT’s 2025 annual meeting proxy statement and the date of NBT’s 2025 annual meeting of stockholders, then the appointment of David J. Nasca (or, in the event of his unavailability, such other person as mutually agreed upon by Evans and NBT) to the boards of directors of NBT and NBT Bank will be effective immediately following their respective annual meetings of stockholders. Mr. Nasca must meet the qualifications for directors set forth in the bylaws of NBT and NBT Bank. Mr. Nasca will serve on the NBT and NBT Bank boards of directors until the next annual meeting following his appointment. If Mr. Nasca is appointed at any time other than immediately following the 2025 annual meeting of stockholders of NBT and NBT Bank, the NBT and NBT Bank boards of directors also will nominate Mr. Nasca for election at the first annual stockholder meeting following his appointment.

No Solicitation of Alternative Transactions (Page 66)

The merger agreement restricts Evans’s ability to solicit or engage in discussions or negotiations with a third party regarding a proposal by such third party to acquire a significant interest in Evans. However, if Evans receives a bona fide, unsolicited written acquisition proposal from a third party that its Board of Directors believes in good faith is, or is reasonably likely to lead to, a proposal (i) on terms which the Evans Board of Directors determines in good faith, after consultation with its financial advisor, to be more favorable from a financial point of view to Evans shareholders than the transactions contemplated by the merger agreement, and

TABLE OF CONTENTS

(ii) that constitutes a transaction that, in the good faith judgment of the Evans Board of Directors, is reasonably likely to be consummated on the terms set forth, taking into account all legal, financial, regulatory and other aspects of such proposal, Evans may furnish non-public information to that third party and engage in negotiations regarding an acquisition proposal with that third party, subject to specified conditions in the merger agreement, if its Board of Directors determines in good faith, after consultation with its outside legal counsel, that such action would be required in order for directors of Evans to comply with their fiduciary duties under applicable law.

Conditions to Completion of the Merger (Page 69)

As more fully described in this proxy statement/prospectus and the merger agreement, the completion of the merger depends on a number of conditions being satisfied or waived, including, but not limited to:

•	shareholders of Evans having approved the merger agreement;

•	NBT and Evans having obtained all regulatory approvals and/or waivers required to consummate the transactions contemplated by the merger agreement and all related statutory waiting periods having expired;

•	the absence of any judgment, order, injunction or decree, or any statute, rule or regulation enacted, entered, promulgated or enforced, preventing, prohibiting or making illegal the consummation of any of the transactions contemplated by the merger agreement;

•	NBT and Evans having each received a legal opinion from their respective counsel regarding treatment of the merger as a “reorganization” for U.S. federal income tax purposes;

•	the representations and warranties of each of NBT and Evans in the merger agreement being accurate, subject to exceptions that would not have a material adverse effect;

•	NBT and Evans having each performed in all material respects all obligations required to be performed by it; and

•	the shares of NBT common stock to be issued in the merger having been approved for listing on the NASDAQ Stock Market.

Termination of the Merger Agreement (Page 71)

NBT and Evans can mutually agree to terminate the merger agreement at any time before the merger has been completed, and either company can terminate the merger agreement if:

•

any regulatory approval required for consummation of the merger and the other transactions contemplated by the merger agreement has been denied by final, nonappealable action of any regulatory authority, or an application for regulatory approval has been permanently withdrawn at the request of a governmental authority;

•	the required approval of the merger agreement by the Evans shareholders is not obtained;

•

the other party materially breaches any of its representations, warranties, covenants or other agreements set forth in the merger agreement (provided that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained in the merger agreement), which breach is not cured within 30 days of written notice of the breach, or by its nature cannot be cured prior to the closing of the merger, and such breach would entitle the non-breaching party not to consummate the merger; or

•	the merger is not consummated by September 15, 2025, unless the failure to consummate the merger by such date is due to a material breach of the merger agreement by the terminating party.

In addition, NBT may terminate the merger agreement if:

•	Evans materially breaches the non-solicitation provisions in the merger agreement;

•	the Evans Board of Directors:

•	fails to recommend approval of the merger agreement, or withdraws, modifies or changes such recommendation in a manner adverse to NBT’s interests; or

TABLE OF CONTENTS

•	recommends, proposes or publicly announces its intention to recommend or propose to engage in an acquisition transaction with any person other than NBT or any of its subsidiaries; or

•	Evans fails to call, give notice of, convene and hold its special meeting.

Termination Fee (Page 71)

Evans has agreed to pay NBT a termination fee of $8.4 million if:

•	NBT terminates the merger agreement as a result of:

•	Evans materially breaching the non-solicitation provisions in the merger agreement;

•	Evans materially breaching the shareholder approval provisions in the merger agreement by failing to call, give notice of, convene and hold the Evans special meeting;

•	the Evans Board of Directors:

○	failing to recommend approval of the merger agreement, or withdrawing, modifying or changing such recommendation in a manner adverse to NBT’s interests; or

○	recommending, proposing or publicly announcing its intention to recommend or propose to engage in an acquisition transaction with any person other than NBT or any of its subsidiaries; or

•

Evans or Evans Bank enters into a definitive agreement relating to an acquisition proposal or consummates an acquisition proposal within 12 months following the termination of the merger agreement by NBT as a result of a willful breach of any representation, warranty, covenant or other agreement by Evans after an acquisition proposal has been publicly announced or otherwise made known to Evans.

Waiver or Amendment of Merger Agreement Provisions (Page 72)

Prior to the effective time of the merger, any provision of the merger agreement may be waived by the party benefited by the provision or amended or modified by a written agreement between NBT and Evans. However, after the Evans special meeting, no amendment will be made which by law requires further approval by the shareholders of Evans without obtaining such approval.

Material U.S. Federal Income Tax Consequences of the Merger (Page 53)

The merger is intended to qualify for U.S. federal income tax purposes as a “reorganization” within the meaning of Section 368(a) of the Code, and it is a condition to our respective obligations to complete the merger that each of Evans and NBT receives a legal opinion to the effect that the merger will so qualify. Assuming the merger so qualifies, Evans shareholders generally will not recognize any gain or loss for U.S. federal income tax purposes on the exchange of their Evans common stock for NBT common stock in the merger, except that such holders will recognize gain (but not loss) to the extent such holders receive cash in lieu of any fractional share of NBT common stock that an Evans shareholder would otherwise be entitled to receive.

Evans shareholders are urged to read the discussion in the section entitled “Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 53 and to consult their tax advisors for a full explanation of the tax consequences of the merger.

Regulatory Approvals Required for the Merger (Page 55)

Approval, or waiver of formal application and approval requirements, by the Federal Reserve Bank of New York and the OCC is required to consummate the merger. As of the date of this proxy statement/prospectus, NBT has not yet received any approvals or waivers from these regulators. While neither NBT nor Evans knows of any reason why the parties would not obtain the approvals or waivers in a timely manner, NBT and Evans cannot be certain when or if such required regulatory approvals or waivers will be obtained.

Accounting Treatment of the Merger (Page 56)

the closing date of the merger and added to those of NBT. Any excess of purchase price over the net fair values of Evans’s assets and liabilities will be recorded as goodwill. Any excess of the fair value of Evans’s net assets over the purchase price will be recognized as earnings by NBT on the closing date of the merger.

Dissenters’ Rights (Page 56)

Evans shareholders are not entitled to appraisal or dissenters’ rights with respect to the merger.

Listing of NBT Common Stock to be Issued in the Merger (Page 22)

NBT common stock will continue to trade on NASDAQ under the trading symbol “NBTB.”

Litigation Related to the Merger (Page 56)

Since the initial filing on October 24, 2024 of the registration statement of which this proxy statement/prospectus is a part, Evans has received demand letters (“Demand Letters”) from three purported Evans shareholders generally alleging that the registration statement filed with the SEC on October 24, 2024 omits material information in violation of the federal securities laws. The shareholders have demanded disclosure of certain additional information pertaining to certain financial projections for Evans, certain information with respect to Piper Sandler’s analysis, and other requested disclosures. Please see the section of this proxy statement/prospectus titled “Risk Factors—Risks Related to the Merger—Since the initial filing on October 24, 2024 of the registration statement of which this proxy statement/prospectus is a part, Evans and the Evans board of directors have received three Demand Letters from purported Evans shareholders, which could result in litigation related to the merger being filed against Evans, the Evans board of directors and/or NBT and the NBT board of directors, and additional demand letters may be received or litigation may be filed against them, which could prevent or delay the completion of the merger or otherwise negatively impact the business and operations of Evans and NBT” on page 19 of this proxy statement/prospectus for more information.

Differences Between Rights of NBT and Evans Shareholders (Page 75)

As a result of the merger, holders of Evans common stock will become holders of NBT common stock. Following the merger, Evans shareholders will have different rights as shareholders of NBT due to the different provisions of the governing documents of NBT and Evans. For additional information regarding the differences between the rights of shareholders of NBT and shareholders of Evans, see “Comparison of Stockholder Rights” beginning on page 75.

Risk Factors (Page 15)

You should consider all the information contained in or incorporated by reference into this proxy statement/prospectus in deciding how to vote for the proposal presented in the proxy statement/prospectus. In particular, you should consider the factors described under “Risk Factors” beginning on page 15.

TABLE OF CONTENTS

RISK FACTORS

In addition to the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed under the caption “Information Regarding Forward-Looking Statements” on page 23, you should carefully read and consider the following risk factors in deciding whether to vote for approval of the merger proposal.

Risks Related to the Merger

Because the number of shares of NBT common stock exchanged per share of Evans common stock is fixed and will not be adjusted in the event of any change in NBT’s share price, the value of the common stock issued by NBT and received by Evans shareholders may be higher or lower at the closing of the merger than when the merger agreement was executed.

Upon the consummation of the merger, each share of common stock of Evans will be converted into 0.91 shares of common stock of NBT. The exchange ratio is fixed in the merger agreement and will not be adjusted for changes in the market price of NBT common stock. Changes in the market price of shares of NBT common stock prior to the merger will affect the market value of the consideration that Evans shareholders will receive on the closing date of the merger. Stock price changes may result from a variety of factors (many of which are beyond NBT’s control), including the following factors:

•	market reaction to the announcement of the merger;

•	changes in NBT’s business, operations, assets, liabilities and prospects;

•	changes in market assessments of the business, operations, financial position and prospects of NBT or the combined company;

•	market assessments of the likelihood that the merger will be completed;

•	interest rates, general market and economic conditions and other factors generally affecting the market price of NBT common stock;

•	the actual or perceived impact of U.S. monetary policy;

•	federal, state and local legislation, governmental regulation and legal developments in the business in which NBT operates; and

•	other factors beyond NBT’s control, including those described or referred to elsewhere in this “Risk Factors” section.

The market price of NBT common stock at the closing of the merger may vary from its price on the date the merger agreement was executed, on the date of this proxy statement/prospectus and on the date of the Evans special meeting. As a result, the market value of the consideration for the merger represented by the exchange ratio also will vary.

Therefore, while the number of shares of NBT common stock to be issued per share of Evans common stock is fixed, Evans shareholders cannot be sure of the market value of the consideration they will receive upon completion of the merger.

Shareholders may be unable to timely sell shares after completion of the merger.

There will be a time period between the completion of the merger and the time at which former Evans shareholders actually receive their shares of NBT common stock. Until shares are received, former Evans shareholders may not be able to sell their NBT shares in the open market and, therefore, may not be able to avoid losses resulting from any decrease, or secure gains resulting from any increase, in the trading price of NBT common stock during this period.

The market price of NBT common stock may decline as a result of the merger and the market price of NBT common stock after the consummation of the merger may be affected by factors different from those affecting the price of NBT common stock or Evans common stock before the merger.

The market price of NBT common stock may decline as a result of the merger if NBT does not achieve the perceived benefits of the merger or the effect of the merger on NBT’s financial results is not consistent with the expectations of financial or industry analysts.

TABLE OF CONTENTS

In addition, the consummation of the merger will result in the combination of two companies that currently operate as independent companies. The business of NBT and the business of Evans differ. As a result, while NBT expects to benefit from certain synergies following the merger, NBT may also encounter new risks and liabilities associated with these differences. Following the merger, shareholders of NBT and Evans will own interests in a combined company operating an expanded business and may not wish to continue to invest in NBT, or for other reasons may wish to dispose of some or all of NBT common stock. If, following the effective time of the merger, large amounts of NBT common stock are sold, the price of NBT common stock could decline.

Further, the results of operations of NBT and the market price of NBT common stock after the merger may be affected by factors different from those currently affecting the independent results of operations of each of NBT and Evans and the market price of NBT common stock. Accordingly, NBT’s historical market prices and financial results may not be indicative of these matters for NBT after the merger.

For a discussion of the businesses of NBT and Evans, and of certain factors to consider in connection with those businesses, see the documents incorporated by reference into this proxy statement/prospectus and referred to under “Where You Can Find More Information” beginning on page 85.

Both Evans and NBT shareholders will have a reduced ownership and voting interest after the merger and will exercise less influence over management of the combined company.

The merger will dilute the ownership position of NBT shareholders and result in Evans shareholders having an ownership stake in the combined company. Upon completion of the merger, each Evans shareholder will become a shareholder of NBT with a percentage ownership of the combined company that is much smaller than such shareholder’s current percentage ownership of Evans. It is expected that the former shareholders of Evans as a group will receive shares in the merger constituting approximately 10.61% of the outstanding shares of NBT common stock immediately after the merger. Furthermore, because shares of NBT common stock will be issued to existing Evans shareholders, current NBT shareholders will have their ownership and voting interests diluted by approximately 10.61%. Accordingly, both Evans and NBT shareholders will have less influence on the management and policies of the combined company than they now have on the management and policies of their respective company.

After the merger is completed, Evans shareholders will become NBT shareholders and will have different rights that may be less advantageous than their current rights.

Upon completion of the merger, Evans shareholders will become NBT shareholders. Differences in Evans’s charter and bylaws and NBT’s charter and bylaws will result in changes to the rights of Evans shareholders who become NBT shareholders. For more information, see “Comparison of Stockholder Rights” beginning on page 75.

Evans will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainty about the effect of the merger on Evans’s employees, suppliers and customers may have an adverse effect on Evans. These uncertainties may impair Evans’s ability to attract, retain and motivate key personnel until the merger is completed, and could cause customers, suppliers and others who deal with Evans to seek to change existing business relationships with Evans. Evans employee retention and recruitment may be particularly challenging prior to the effective time of the merger, as employees and prospective employees may experience uncertainty about their future roles with NBT.

The pursuit of the merger and the preparation for the integration may place a significant burden on management and internal resources. Any significant diversion of management attention away from ongoing business and any difficulties encountered in the transition and integration process could affect the financial results of Evans and, following the merger, NBT. In addition, the merger agreement requires that Evans operate in the ordinary course of business consistent with past practice and restricts Evans from taking certain actions prior to the effective time of the merger or termination of the merger agreement without NBT’s written consent. These restrictions may prevent Evans from retaining existing customers or pursuing attractive business opportunities that may arise prior to the completion of the merger.

The merger agreement contains provisions that limit Evans’s ability to pursue alternatives to the merger and may discourage other companies from trying to acquire Evans.

The merger agreement contains covenants that restrict Evans’s ability to, directly or indirectly, initiate, solicit, induce, knowingly encourage, or knowingly facilitate inquiries, offers or proposals with respect to, or, subject to

TABLE OF CONTENTS

certain exceptions generally related to the exercise of fiduciary duties by the Evans Board of Directors, engage in any negotiations concerning, or provide any confidential or non-public information or data relating to, any alternative acquisition proposals. Additionally, the merger agreement provides for an $8.4 million termination fee payable by Evans to NBT under certain circumstances. Such provisions may discourage a potential third-party acquirer that might have an interest in acquiring all or a significant part of Evans from pursuing such acquisition. For more information, see “The Merger Agreement—No Solicitation” on page 66 and “The Merger Agreement—Termination Fee” on page 71.

The fairness opinion received by the Evans Board of Directors from Piper Sandler prior to execution of the merger agreement does not reflect changes in circumstances subsequent to the date of the fairness opinion.

Piper Sandler, Evans’s financial advisor in connection with the proposed merger, delivered to the Evans Board of Directors its opinion on September 9, 2024 to the effect that, as of such date and subject to the assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler as set forth in the opinion, the merger consideration set forth in the merger agreement was fair, from a financial point of view, to the holders of Evans common stock. The opinion speaks only as of the date of the opinion. The opinion does not reflect changes that may occur or may have occurred after the date of the opinion, including changes to the operations and prospects of NBT or Evans, changes in general market and economic conditions or regulatory or other factors. Any such changes may materially alter or affect the relative values of NBT and Evans.

The merger agreement may be terminated in accordance with its terms and the merger may not be completed.

NBT and Evans can mutually agree to terminate the merger agreement at any time before the merger has been completed, and either company can terminate the merger agreement if:

•

•	the required approval of the merger agreement by the Evans shareholders is not obtained;

•

•	the merger is not consummated by September 15, 2025, unless the failure to consummate the merger by such date is due to a material breach of the merger agreement by the terminating party.

In addition, NBT may terminate the merger agreement if:

•	Evans materially breaches the non-solicitation provisions in the merger agreement; or

•	the Evans Board of Directors:

•	fails to recommend approval of the merger agreement, or withdraws, modifies or changes such recommendation in a manner adverse to NBT’s interests;

•	recommends, proposes or publicly announces its intention to recommend or propose to engage in an acquisition transaction with any person other than NBT or any of its subsidiaries; or

•	Evans fails to call, give notice of, convene and hold its special meeting.

See the section of this proxy statement/prospectus entitled “The Merger Agreement—Termination” beginning on page 71 for a further discussion of the circumstances under which the merger agreement could be terminated.

TABLE OF CONTENTS

The merger is subject to a number of conditions, including the receipt of waivers and/or approvals from governmental authorities, that may delay the merger or adversely impact NBT’s and Evans’s ability to complete the merger.

The completion of the merger is subject to the satisfaction or waiver of a number of conditions. Before the merger may be completed, certain approvals, waivers or consents must be obtained from federal governmental authorities, including the Federal Reserve Bank of New York and the OCC. Satisfying the requirements of these governmental authorities may delay the date of completion of the merger. In addition, these governmental authorities may include conditions on the completion of the merger or require changes to the terms of the merger. While it is currently anticipated that the merger will be completed promptly following the receipt of all required regulatory and shareholder approvals, there can be no assurance that the conditions to closing will be satisfied in a timely manner or at all, or that an effect, event, development or change will not transpire that could delay or prevent these conditions from being satisfied or impose additional costs on or limit the revenues of NBT following the merger, any of which might have a material adverse effect on NBT following the merger. The parties are not obligated to complete the merger should any regulatory approval contain a condition, restriction or requirement that the NBT Board of Directors reasonably determines in good faith would, individually or in the aggregate, materially reduce the benefits of the merger to such a degree that NBT would not have entered into the merger agreement had such condition, restriction or requirement been known at the date of the merger agreement.

NBT and Evans cannot provide any assurances with respect to the timing of the closing of the merger, whether the merger will be completed at all and when Evans shareholders would receive the consideration for the merger, if at all.

Failure to complete the merger could negatively impact the stock prices and future business and financial results of NBT and Evans.

Completion of the merger is subject to the satisfaction or waiver of a number of conditions, including approval by Evans shareholders of the merger. NBT or Evans cannot guarantee when or if these conditions will be satisfied or that the merger will be successfully completed. The consummation of the merger may be delayed, the merger may be consummated on terms different than those contemplated by the merger agreement, or the merger may not be consummated at all. If the merger is not completed, the ongoing businesses of NBT and Evans may be adversely affected, and NBT and Evans will be subject to several risks, including the following:

•	Evans may be required, under certain circumstances, to pay NBT a termination fee of $8.4 million under the merger agreement;

•	NBT and Evans could incur substantial costs relating to the proposed merger, such as legal, accounting, financial advisor, filing, printing and mailing fees;

•	under the merger agreement, Evans is subject to certain restrictions on the conduct of its business prior to completing the merger, which may adversely affect its ability to execute certain of its business strategies; and

•	NBT’s and Evans’s management’s and employees’ attention may be diverted from their day-to-day business and operational matters as a result of efforts relating to the attempt to consummate the merger.

In addition, if the merger is not completed, NBT and Evans may experience negative reactions from the financial markets and from their respective customers and employees. NBT and Evans also could be subject to litigation related to any failure to complete the merger or to enforcement proceedings commenced against NBT or Evans to perform their respective obligations under the merger agreement. If the merger is not completed, NBT and Evans cannot assure their respective shareholders that the risks described above will not materialize and will not materially affect the stock prices and business and financial results of NBT and Evans.

TABLE OF CONTENTS

Since the initial filing on October 24, 2024 of the registration statement of which this proxy statement/prospectus is a part, Evans and the Evans board of directors have received three Demand Letters from purported Evans shareholders, which could result in litigation related to the merger being filed against Evans, the Evans board of directors and/or NBT and the NBT board of directors, and additional demand letters may be received or litigation may be filed against them, which could prevent or delay the completion of the merger or otherwise negatively impact the business and operations of Evans and NBT.

The shareholders who provided the Demand Letters, or other shareholders, may initiate litigation against Evans, the Evans board of directors, NBT and the NBT board of directors, and it is possible that Evans, the Evans board of directors, NBT or the NBT board of directors may receive further demand letters alleging wrongdoing with respect to the merger.

One of the conditions to the closing is that no order, injunction or decree issued by any court or governmental entity of competent jurisdiction or other legal restraint preventing the consummation of any of the transactions contemplated by the merger agreement be in effect. If any plaintiff were successful in obtaining an injunction prohibiting Evans or NBT from completing the transactions contemplated by the merger agreement, then such injunction may delay or prevent the effectiveness of the merger and could result in significant costs to Evans and/or NBT, including any cost associated with the indemnification of directors and officers of each company. Evans and NBT may also incur costs in connection with the defense or settlement of any shareholder lawsuit filed in connection with the merger. Such litigation could have an adverse effect on the financial condition and results of operations of Evans and NBT and could prevent or delay the completion of the merger.

Certain of Evans’s directors and executive officers may have interests in the merger that are different from, or in addition to, those of Evans’s shareholders.

Evans shareholders should be aware that some of Evans’s directors and executive officers may have interests in the merger and have arrangements that are different from, or in addition to, those of Evans shareholders. These interests and arrangements may create potential conflicts of interest. The Evans Board of Directors was aware of these interests and considered them, among other matters, when making its decision to approve the merger agreement and recommend that Evans’s shareholders vote to approve the merger proposal. For a more complete description of these interests, please see “The Merger—Interests of Certain Evans Directors and Executive Officers in the Merger” beginning on page 48.

Risks Related to the Combined Company if the Merger is Completed

The integration of NBT and Evans will present significant challenges and expenses that may result in the combined business not operating as effectively as expected, or in the failure to achieve some or all of the anticipated benefits of the transaction.

The benefits and synergies expected to result from the proposed transaction will depend in part on whether the operations of Evans can be integrated in a timely and efficient manner with those of NBT. NBT will face challenges and costs in consolidating its functions with those of Evans, and integrating the organizations, procedures and operations of the two businesses. The integration of NBT and Evans will be complex and time-consuming, and the management of both companies will have to dedicate substantial time and resources to it. These efforts could divert management’s focus and resources from serving existing customers or other strategic opportunities and from day-to-day operational matters during the integration process. Failure to successfully integrate the operations of NBT and Evans could result in the failure to achieve some of the anticipated benefits from the transaction, including cost savings and other operating efficiencies, and NBT may not be able to capitalize on the existing relationships of Evans to the extent anticipated, or it may take longer, or be more difficult or expensive than expected to achieve these goals. This could have an adverse effect on the business, results of operations, financial condition or prospects of NBT and NBT Bank after the transaction.

TABLE OF CONTENTS

Unanticipated costs relating to the merger could reduce NBT’s future earnings per share.

NBT has incurred substantial legal, accounting, financial advisory and other merger-related costs, and NBT’s management has devoted considerable time and effort in connection with the merger. If the merger is not completed, NBT will bear certain fees and expenses associated with the merger without realizing the benefits of the merger. If the merger is completed, NBT expects to incur substantial expenses in connection with integrating the business, operations, network, systems, technologies, policies and procedures of the two companies. The fees and expenses may be significant and could have an adverse impact on NBT’s results of operations.

NBT believes that it has reasonably estimated the likely costs of integrating the operations of NBT and Evans, and the incremental costs of operating as a combined company. However, it is possible that unexpected transaction costs such as taxes, fees or professional expenses or unexpected future operating expenses such as increased personnel costs or increased taxes, as well as other types of unanticipated adverse developments, could have a material adverse effect on the results of operations and financial condition of the combined company. If unexpected costs are incurred, the merger could have a dilutive effect on NBT’s earnings per share. In other words, if the merger is completed, the earnings per share of NBT common stock could be less than anticipated or even less than if the merger had not been completed.

Estimates as to the future value of the combined company are inherently uncertain. You should not rely on such estimates without considering all of the information contained or incorporated by reference into this proxy statement/prospectus.

Any estimates as to the future value of the combined company, including estimates regarding the earnings per share of the combined company, are inherently uncertain. The future value of the combined company will depend upon, among other factors, the combined company’s ability to achieve projected revenue and earnings expectations and to realize the anticipated synergies described in this proxy statement/prospectus, all of which are subject to the risks and uncertainties described in this proxy statement/prospectus, including these risk factors. Accordingly, you should not rely upon any estimates as to the future value of the combined company, whether made before or after the date of this proxy statement/prospectus by NBT’s and Evans’s respective management or affiliates or others, without considering all of the information contained or incorporated by reference into this proxy statement/prospectus.

Following the merger, NBT may not continue to pay dividends at or above the rate currently paid by NBT.

Following the merger, NBT shareholders may not receive dividends at the same rate that they did as NBT shareholders prior to the merger for various reasons, including the following:

•	NBT may not have enough cash to pay such dividends due to changes in its cash requirements, capital spending plans, cash flow or financial position;

•	decisions on whether, when and in what amounts to make any future dividends will remain at all times entirely at the discretion of the NBT Board of Directors, which reserves the right to change NBT’s dividend practices at any time and for any reason; and

•	the amount of dividends that NBT’s subsidiaries may distribute to NBT may be subject to restrictions imposed by state law and restrictions imposed by the terms of any current or future indebtedness that these subsidiaries may incur.

NBT shareholders will have no contractual or other legal right to dividends that have not been declared by the NBT Board of Directors.

Risks Relating to NBT’s Business

You should read and consider risk factors specific to NBT’s business that may affect the combined company after the merger. These risks are described in the “Risk Factors” section of NBT’s Annual Report on Form 10-K for the year ended December 31, 2023, and any subsequent updates included in NBT’s Quarterly Reports on Form 10-Q and in other documents incorporated by reference into this proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 85.

November 1, 2024	$44.56	$39.54	$40.55

(1)	Calculated by multiplying the closing price of NBT common stock as of the specified date by the exchange ratio of 0.91

The market value of the NBT common stock to be issued in exchange for shares of Evans common stock upon the completion of the merger will not be known at the time of the Evans special meeting. Evans shareholders are encouraged to obtain current market quotations for NBT common stock and Evans common stock and to review carefully the other information contained in this proxy statement/prospectus or incorporated by reference in this proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 85.

The holders of NBT common stock receive dividends as and when declared by the NBT Board of Directors out of statutory surplus or from net profits. Following the completion of the merger, subject to approval and declaration by the NBT Board of Directors, NBT expects to continue paying quarterly cash dividends on a basis consistent with past practice. The current annualized rate of distribution on a share of NBT common stock is $1.36 per share. However, the payment of dividends by NBT is subject to numerous factors, and no assurance can be given that NBT will pay dividends following the completion of the merger or that dividends will not be reduced in the future.

Evans currently pays regular semi-annual dividends of $0.66 per share. Except for these regular semi-annual dividends, the merger agreement does not permit Evans to pay cash dividends without NBT’s prior written consent.

Following the original mailing of the proxies and other soliciting materials, Evans and its agents may also solicit proxies by mail, telephone, facsimile or in person. No additional compensation will be paid to directors, officers or other employees of Evans for making these solicitations.

Evans has retained a proxy solicitation firm, Alliance Advisors, LLC, to aid it in the solicitation process. Evans estimates it will pay Alliance Advisors, LLC a fee of approximately $20,000 plus certain expenses and has agreed to indemnify Alliance Advisors, LLC against certain losses. Evans intends to reimburse persons who hold Evans common stock of record but not beneficially, such as brokers, custodians, nominees and fiduciaries, for their reasonable expenses in forwarding copies of proxies and other soliciting materials to, and requesting authority for the exercise of proxies from, the persons for whom they hold the shares.

General

On September 9, 2024, NBT, NBT Bank, Evans and Evans Bank entered into an Agreement and Plan of Merger (the “merger agreement”) pursuant to which (i) Evans will merge with and into NBT, with NBT as the surviving entity, and (ii) Evans Bank will merge with and into NBT Bank, with NBT Bank as the surviving entity.

Upon completion of the merger, holders of Evans common stock (other than stock held by NBT or Evans) will receive 0.91 shares of NBT common stock for each share of Evans common stock they own on the effective date of the merger. Evans shareholders will also receive cash in lieu of any fractional shares they would have otherwise received in the merger.

See “The Merger Agreement” beginning on page 59, for additional and more detailed information regarding the legal documents that govern the merger, including information about the conditions to the merger and the provisions for terminating or amending the merger agreement.

Background of the Merger

On March 19, 2024, at a regularly scheduled meeting of the Evans Board of Directors at which representatives of Piper Sandler were in attendance, and following a year-long review of long term strategies, prospects and strategic alternatives, the Evans Board of Directors determined to explore the value that could be delivered to shareholders through a business combination with a strategic partner. The Evans Board of Directors discussed several bank holding companies that in the past had expressed an interest in Evans should it ever pursue a merger transaction, and which previously had been identified by Evans as viable strategic partners. Included among these companies was NBT. The Evans Board of Directors authorized David Nasca, President and Chief Executive Officer of Evans, to reengage with executives of these companies to determine if they remained interested in a possible strategic combination and, in consultation with Piper Sandler to consider other potential strategic partners based on an analysis of an ability to pay and likely interest in an acquisition of a $2 billion bank operating in upstate New York.

In April, May and early June, 2024, Mr. Nasca met or talked with executives of four bank holding companies, each of which operated in the upstate New York marketplace, or in a contiguous marketplace, and each of which in the past had expressed an interest in Evans should it pursue a merger transaction. Mr. Nasca met with John Watt, former President and Chief Executive Officer of NBT, and Scott Kingsley, President and Chief Executive Officer of NBT, on April 19, 2024, and had a follow-up telephone call with Mr. Kingsley on May 6, 2024. Mr. Nasca received confirmation of continued interest in a possible merger transaction with Evans from executives of each of the four bank holding companies, including NBT.

On June 18, 2024, at a regularly scheduled meeting of the Evans Board of Directors at which Piper Sandler and Luse Gorman were in attendance, Piper Sandler and Mr. Nasca provided an overview to the Evans Board of Directors of the steps that had been taken since the March 19 meeting of the Evans Board of Directors to determine if there was interest from third parties in terms of moving forward with a possible process for a strategic acquisition of Evans. Piper Sandler and Mr. Nasca reported on the favorable feedback received from the four bank holding companies. Each of these companies had a stock that traded at a premium to book value and were considered to have a strong likelihood of receiving regulatory approval of a merger transaction with Evans. As to each of the companies, Piper Sandler provided a preliminary capacity to pay analysis, along with a financial and management overview. Piper Sandler also noted to the Board of Directors that a wider universe of bank holding companies had been considered in their review, but were eliminated from consideration for a variety of financial reasons, while certain other companies were eliminated based on several “no name” discussions with Piper Sandler that confirmed to Piper Sandler that these companies were not interested in the mergers and acquisitions market at that time. At this meeting, Luse Gorman discussed the fiduciary duties of the Evans Board of Directors, in particular in the context of a merger and acquisition transaction. Piper Sandler outlined a process that would involve entering into nondisclosure agreements with each of the four bank holding

TABLE OF CONTENTS

companies that had been contacted, their conducting preliminary due diligence on Evans and their submission of an indication of interest addressing key transaction terms. After review and discussion, the Evans Board of Directors authorized Evans management and Piper Sandler to move forward with the four bank holding companies and commence a process for a possible strategic acquisition of Evans.

Following the June 18 meeting of the Evans Board of Directors, each of the four bank holding companies, including NBT, entered into a nondisclosure agreement with Evans. The nondisclosure agreements included certain standstill provisions prohibiting each company from proposing or seeking to acquire Evans other than through the indication of interest process, which prohibitions terminated once Evans entered into an agreement to be acquired by a third party.

A virtual data room was established by Evans, populated with preliminary non-public due diligence information, and opened to the four bank holding companies on June 23, 2024.

On June 26, 2024, Piper Sandler provided bidding instructions for an indication of interest to each of the four bank holding companies and requested that the indication of interest be returned by July 12, 2024.

Prior to the July 12^th deadline, two of the bank holding companies informed Piper Sandler that they would not proceed further with the submission of an indication of interest.

On July 12, 2024, NBT and one other bank holding company (referred to as “Company B”) submitted an indication of interest.

On July 16, 2024, at a regularly scheduled meeting of the Evans Board of Directors at which representatives of Piper Sandler and Luse Gorman were in attendance, Piper Sandler reviewed the two indications of interest that were submitted by NBT and Company B. Each indication of interest proposed an all stock merger transaction. The indication of interest submitted by NBT proposed a fixed exchange ratio of 0.9011 shares of NBT common stock for each share of Evans common stock, which implied a deal price per share of Evans common stock of between $35.26 and $37.25, based on NBT’s closing stock price of $41.34 on July 11, 2024, and a five-day average closing stock price of NBT common stock of $39.13. The indication of interest submitted by Company B proposed a per share value of $35-$36 for each share of Evans common stock, with a fixed exchange ratio to be determined closer to transaction signing. The other proposed terms in the indications of interest submitted by NBT and Company B were substantially similar, with Company B proposing to appoint Mr. Nasca to the board of directors of Company B and its subsidiary bank, and NBT proposing to appoint one mutually agreed upon Evans director to the NBT and NBT Bank boards of directors. Piper Sandler reviewed with the Evans Board of Directors a financial analysis of each of the indications of interest and of each of NBT and Company B. Luse Gorman again reviewed with the Evans Board of Directors the fiduciary duties applicable to the transaction. Following discussion, the Evans Board of Directors directed Piper Sandler to request NBT to increase its proposed exchange ratio of 0.9011 shares of NBT common stock per share of Evans common stock, with the understanding that if the exchange ratio was increased, Evans was prepared to move forward with NBT’s indication of interest, with an exclusivity period for negotiating a definitive agreement. A special meeting of the Evans Board of Directors was scheduled for Friday, July 19, 2024.

Following the July 16^th meeting of the Evans Board of Directors, and as directed by the Evans Board of Directors, Piper Sandler advised Stephens Inc. (“Stephens”), NBT’s financial advisor for the transaction, of Evans’ interest in the indication of interest submitted by NBT, and passed along the Evans Board of Directors’ request that the exchange ratio be increased in order for Evans to move forward with NBT’s indication of interest and an exclusivity agreement for the negotiation of a definitive agreement. Piper Sander advised Stephens that an Evans Board of Directors meeting was scheduled for late in the afternoon on July 19, 2024, and that any increase in the exchange ratio should be reflected in an updated indication of interest to be submitted before the July 19^th meeting. In response, Stephens informed Piper Sandler that NBT was prepared to increase the exchange ratio to 0.92 shares of NBT common stock for each share of Evans common stock.

Following the July 16^th meeting, Piper Sandler also communicated with the financial advisor for Company B, and indicated that the Evans Board of Directors consideration of its indication of interest was complicated by the fact that the indication of interest was stated in the form of a price range, which did not enable Evans to capture the appreciation in Company B’s stock price since the submission of the indication of interest. Piper Sandler indicated that it had converted the price range included in Company B’s indication of interest into an implied

TABLE OF CONTENTS

exchange ratio of between 2.89 and 3.08 shares of Company B common stock for each share of Evans common stock, which resulted in a valuation of $40.75 per share of Evans common stock using the upper end of the implied exchange ratio. Company B’s financial advisor concurred in this analysis.

On July 18, 2024, the chief executive officer of Company B telephoned Mr. Nasca and stated that he was prepared to seek approval from the board of directors of Company B to increase the exchange ratio further, to up to 3.3 shares of Company B common stock for each share of Evans common stock, if Evans would assure him that the increased exchange ratio would be accepted. Mr. Nasca responded that he could not provide such assurance, which not only would require action from the Evans Board of Directors, but first would require action from the board of directors of Company B and a revised formal indication of interest.

Also on July 18, 2024, Piper Sandler and the financial advisor for Company B had a telephone conversation, and the financial advisor for Company B confirmed Company B’s interest in seeking board approval for an increased exchange ratio if Evans could provide assurance that the increased exchange ratio would be accepted. Piper Sandler advised the financial advisor for Company B that such assurance could only be provided by the Evans Board of Directors, and that the Evans Board of Directors was meeting on July 19, 2024 and would consider any revised indication of interest that Company B submitted. No revised indication of interest was submitted by Company B.

On July 19, 2024, before the Evans Board of Directors meeting, NBT submitted an updated indication of interest reflecting an increase in the exchange ratio to 0.92 shares of NBT common stock per share of Evans common stock.

On July 19, 2024, at a special meeting of the Evans Board of Directors at which representatives of Piper Sandler and Luse Gorman were in attendance, Piper Sandler reviewed a summary financial analysis of the indications of interests submitted by NBT and Company B. Using the upper end of the implied exchange ratio reflected in Company B’s indication of interest, Company B’s indication of interest resulted in a transaction value of $40.53 per share of Evans common stock. Based on the increased exchange ratio of 0.92 shares of NBT common stock per share of Evans common stock reflected in the updated indication of interest submitted by NBT, NBT’s updated indication of interest resulted in a transaction value of $41.78 per share of Evans common stock, based on the closing stock price of NBT common stock on July 18, 2024 of $45.41. Piper Sandler also provided a summary financial analysis of the verbal indication provided by Company B as to an exchange ratio of up to 3.3 shares of Company B common stock for each share of Evans common stock, which would have resulted in a transaction value of $43.40 per share of Evans common stock.

Noting that Company B had indicated that its board had not authorized an increased exchange ratio and that a revised indication of interest with an increased exchange ratio had not in fact been submitted by Company B, and taking into account the Evans Board of Directors’ evaluation of the qualitative factors relating to NBT and Company B, the Evans Board of Directors determined to authorize Piper Sandler and Mr. Nasca to inform NBT that Evans was prepared to move forward with the execution of its indication of interest and a sixty day exclusivity agreement for the negotiation of a definitive agreement. On July 19, following this Board meeting, NBT and Evans executed the indication of interest, which included the sixty day exclusivity period.

During the balance of July and August, 2024, Evans and NBT conducted a due diligence review of the other.

On August 7, 2024 counsel for NBT delivered to Luse Gorman the first draft of a proposed merger agreement, which was provided to Evans. Thereafter, and continuing through September 4, 2024, the parties and their counsel negotiated the terms of the merger agreement and related transaction documents, reflecting discussions between the parties regarding transaction terms.

On August 26, 2024, the Corporate Governance and Nominating Committee of the Evans Board of Directors met and determined to recommend to the Evans Board of Directors that the merger agreement should specify that David Nasca will be appointed to the board of directors of NBT and NBT Bank. By unanimous written consent dated August 30, 2024, the Evans Board of Directors approved and adopted this recommendation. This was communicated to NBT, and reflected in revised transaction documents.

On August 30, 2024, Mr. Kingsley spoke with Mr. Nasca via telephone to express concerns emanating from due diligence as to certain additional costs of the transaction. Mr. Kingsley discussed that, as a result of these concerns, NBT was seeking a reduction of the exchange ratio to 0.9011 shares of NBT common stock for each share of Evans common stock, which exchange ratio was included in NBT’s initial indication of interest.

TABLE OF CONTENTS

On September 3, 2024, Mr. Nasca and Mr. Kingsley again spoke via telephone regarding the exchange ratio. Following discussion, Mr. Nasca and Mr. Kingsley agreed to an exchange ratio of 0.91 shares of NBT common stock for each share of Evans common stock, subject to the approval of the Evans Board of Directors.

Between September 1 and September 4, 2024, Luse Gorman and Hogan Lovells exchanged drafts of and finalized the terms of the merger agreement, the related disclosure schedules, the plan of bank merger and the voting agreement (the “transaction documents”).

On September 4, 2024, the Evans Board of Directors were provided with copies of the definitive transaction documents, as well as an overview of the principal terms of the definitive merger agreement.

On September 6, 2024, at a special meeting of the Evans Board of Directors at which representatives of Piper Sandler and Luse Gorman were in attendance, Mr. Nasca informed the Evans Board of Directors of his discussions with Mr. Kingsley and the revised exchange ratio of 0.91 shares of NBT common stock for each share of Evans common stock. Mr. Nasca stated his view that the revised exchange ratio represented a strong offer that provided shareholders with a significant premium to the then current stock price. Piper Sandler reviewed its fairness opinion presentation, based on the exchange ratio of 0.91 shares of NBT common stock for each share of Evans common stock, a copy of which presentation had been provided to the Evans Board of Directors in advance of the meeting. Piper Sandler advised the Evans Board of Directors that Piper Sandler was prepared to render its opinion to the effect that, as of such date and subject to the procedures followed, assumptions made, matters considered and the qualifications and limitations on the review undertaken by it as set forth in its opinion, the exchange ratio of 0.91 shares of NBT common stock for each share of Evans common stock was fair, from a financial point of view, to the holders of Evans’ common stock. See “PROPOSAL 1–The Merger–Opinion of Piper Sandler & Co., Financial Advisor to Evans” beginning on page 37 and Annex B. Luse Gorman discussed the fiduciary duties of the board of directors applicable to the transaction and then reviewed in detail the terms of the merger agreement and related documents.

Following discussion, the Evans Board of Directors agreed to vote on the merger agreement and related transactions at a special meeting of the Evans Board of Directors to be held on September 9, 2024.

On September 9, at a special meeting of the Evans Board of Directors at which representatives of Piper Sandler and Luse Gorman were in attendance, Piper Sandler stated that it was prepared to render its fairness opinion dated as of September 9, 2024. Luse Gorman noted that no further revisions to the transaction documents had been made. After discussion, the Evans Board of Directors unanimously voted to approve the merger agreement with NBT and to recommend its approval to the Evans shareholders. Evans and NBT executed the merger agreement, entered into the voting agreements with the directors and executive officers, and publicly announced the transaction.

Evans’s Reasons for the Merger

After careful consideration, the Evans Board of Directors, at a special meeting held on September 9, 2024, unanimously (i) determined that the merger agreement and the transactions contemplated thereby, including the merger, are in the best interests of Evans and its shareholders, (ii) declared the merger agreement advisable, (iii) approved the execution and delivery of the merger agreement and the consummation of the transactions contemplated thereby, including the merger, (iv) directed that the approval of the merger agreement be submitted to holders of Evans common stock and (v) recommended that the holders of Evans common stock vote their shares to approve the merger agreement. Accordingly, the Evans Board of Directors unanimously recommends that Evans shareholders vote “FOR” the merger proposal, “FOR” the Evans compensation proposal and “FOR” the adjournment proposal.

In reaching its decision to approve and adopt the merger agreement and the transactions contemplated thereby, including the merger, and to recommend that Evans’s shareholders approve the merger proposal and compensation proposal, the Evans Board of Directors evaluated the merger agreement, the merger and the other transactions contemplated by the merger agreement in consultation with Evans’s management, as well as with Evans’s legal and financial advisors, and considered a number of factors, including the following:

•	each of Evans’s and NBT’s business, operations, financial condition, geographic footprint, stock performance, asset quality, earnings and prospects, and legal and regulatory status;

•	the historical performance of each of Evans’s and NBT’s common stock, including that NBT’s common stock trades at a premium to book value;

TABLE OF CONTENTS

•	the historical payment of dividends by each of Evans and NBT;

•	the strategic fit of the business lines and the operating philosophies of the two companies;

•	that the companies’ separate market areas, earnings and prospects create the opportunity for the combined company to leverage complementary revenue streams and cost savings and to have superior future earnings and prospects compared to Evans’s earnings and prospects on a standalone basis;

•	the composition of the loan portfolio and the commercial real estate concentration ratio of the combined company;

•

the anticipated financial impact of the transaction on the combined company, including the expected impact on key financial metrics (including tangible book value per share, return on average assets, return on average tangible common equity, and efficiency ratio), regulatory capital ratios, earnings per share accretion, cost savings, and increase in pro forma capital base;

•	the compatibility of the corporate cultures and leadership philosophies of Evans and NBT;

•	the overall strength, experience and leadership of the management team of the combined company;

•

the current and prospective environment in the financial services industry in which Evans operates, including national and local economic conditions, the interest rate environment and various fluctuations in interest rates, the regulatory environment, increased operating costs resulting from regulatory and compliance mandates, increasing competition from both banks and non-bank financial and financial technology firms, current financial market conditions and the likely effects of these factors on Evans’s and the combined company’s potential growth, development, productivity and strategic options, and the execution risks of attempting to address the foregoing considerations as a standalone entity;

•	its views with respect to the strategic alternatives potentially available to Evans, including continuing as a standalone company focusing exclusively on organic growth, pursuing other acquisitions or business combinations, and other transactions involving the sale of Evans;

•	the fact that 100% of the merger consideration will be in NBT common stock, which offers Evans’s shareholders the opportunity to participate as shareholders of NBT in the future earnings and performance of the combined company;

•	the fact that the exchange ratio is fixed, which the Evans Board of Directors believed was consistent with market practice for transactions of this type and with the strategic purpose of the transaction;

•	that Evans shareholders would own approximately 9.7% of the combined company’s common stock;

•	that one member of Evans’s Board of Directors, Evans’s President and Chief Executive Officer, David J. Nasca, would join the Board of Directors of the combined company;

•

the fact that the combined company would continue to be publicly held following the merger and would continue to be traded on the NASDAQ Stock Market, providing the combined company’s shareholders with continued access to a public trading market, and that shareholders would be expected to have increased liquidity for their shares as a result of the higher market capitalization of the combined company, the significantly expanded shareholder base and the potential increase in interest from institutional investors and securities analysts;

•

the belief that, while no assurances could be given, the business and financial advantages contemplated in connection with the merger were likely to be achieved within a reasonable time frame, particularly in light of the fact that NBT has merger integration experience due to successfully completed acquisitions and data processing conversions;

•	the expectation that the transaction will be generally tax-free for United States federal income tax purposes to Evans’s shareholders;

•

the fact that the implied value of the merger consideration of $42.11 per share of Evans common stock, based on the closing price of NBT common stock as of September 6, 2024 of $46.28, represented an 18.3% premium over the closing price of Evans common stock on September 6, 2024 (the last trading day prior to the board meeting to approve the merger);

•

the financial analysis prepared by Piper Sandler and the opinion delivered to the Evans Board of Directors by Piper Sandler on September 9, 2024, and based upon and subject to the assumptions made, procedures followed, matters considered, and qualifications and limitations on the review undertaken by Piper Sandler in preparing the opinion, as to the fairness, from a financial point of view, of the exchange ratio in the merger pursuant to the merger agreement to the holders of Evans’s outstanding common stock, as more fully described below in the section titled “—Opinion of Piper Sandler & Co., Financial Advisor to Evans;”

•	the fact that Evans’s shareholders will have the opportunity to vote to approve the merger agreement and transactions contemplated thereby;

•	its review with representatives of its financial advisor of the financial terms of the merger agreement and its review with its legal advisors of the other terms of the merger agreement, including the representations, covenants, conditions and deal protection and termination provisions;

•	the right of the Evans Board of Directors under the merger agreement to withdraw or modify its recommendation to Evans shareholders that they approve the merger proposal under certain circumstances; and

•	the right of Evans to terminate the merger agreement under certain circumstances, as more fully described under “The Merger Agreement—Termination.”

The Evans Board of Directors also considered the potential risks associated with the transaction. The Evans Board of Directors concluded that the anticipated benefits of combining with NBT were likely to outweigh these risks substantially. These potential risks included:

•	the diversion of management focus and resources from other strategic opportunities and operational matters while working to implement the merger transaction and integrate the two companies;

•	the possibility of the combined company encountering difficulties in achieving cost savings and synergies in the amounts currently estimated or within the timeframe currently contemplated;

•	the possibility of encountering difficulties in successfully integrating the businesses, operations and workforces of Evans and NBT;

•	the possibility that the merger and the related integration process could result in the loss of key employees, in the disruption of Evans’s ongoing business and in the loss of customers for the combined company;

•	the substantial costs to be incurred in connection with the merger, including the costs of integrating the businesses of Evans and NBT, transaction fees, expenses and other payments that will or may arise from the merger;

•	the regulatory and other approvals required in connection with the merger and the bank merger and the risk that such regulatory approvals may not be received in a timely manner or may impose unacceptable conditions;

•

the possibility that the merger may not be completed despite the combined efforts of Evans and NBT, or that completion may be unduly delayed, even if the required regulatory approvals are obtained and the requisite approvals are obtained from Evans’s shareholders, including as a result of factors outside Evans’s and NBT’s control;

•	the potential for legal claims challenging the merger;

•	the potential for the value of the merger consideration to be received by holders of shares of Evans common stock to be adversely affected by a decrease in the trading price of NBT common stock;

•

the fact Evans’s directors and executive officers may have interests in the merger that are different from or in addition to those of its shareholders generally, as more fully described in the section titled “PROPOSAL 1—The Merger—Interests of Evans’s Directors and Executive Officers in the Merger;”

•	the fact that Evans may be obligated to pay NBT a termination fee of $8.4 million if the merger with NBT is not completed under certain circumstances, as more fully described in the section titled “The Merger Agreement—Termination Fee;”

TABLE OF CONTENTS

•	the fact that Evans’s common shareholders would not be entitled to appraisal or dissenters’ rights in connection with the merger;

•

the restrictions on the conduct of Evans’s business during the period between execution of the merger agreement and the consummation of the merger, which could potentially delay or prevent Evans from undertaking business opportunities that might arise or certain other actions it might otherwise take with respect to its operations absent the pendency of the merger; and

•	the other risks of the type and nature described in the sections titled “Risk Factors” and “Information Regarding Forward-Looking Statements,” including but not limited to the risks described in the section titled “Risk Factors—Risks Related to the Merger.”

In considering the recommendation of the Evans Board of Directors, you should be aware that certain directors and executive officers of Evans may have interests in the merger that are different from, or in addition to, interests of shareholders of Evans generally and may create potential conflicts of interest. The Evans Board of Directors was aware of these interests and considered them when evaluating and negotiating the merger agreement, the merger and the other transactions contemplated by the merger agreement, and in recommending to Evans’s shareholders that they vote in favor of the merger proposal. See “PROPOSAL 1—The Merger— Interests of Evans’s Directors and Executive Officers in the Merger” beginning on page 48 for more information.

The foregoing discussion of the material information and factors considered by the Evans Board of Directors is not intended to be exhaustive and may not include all of the factors considered by the Evans Board of Directors. In view of the variety of factors considered in connection with its consideration of the merger and the other transactions contemplated by the merger agreement, and the complexity of these matters, the Evans Board of Directors did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The above factors are not listed in any particular order of priority. The Evans Board of Directors considered all these factors as a whole.

It should be noted that this explanation of the reasoning of the Evans Board of Directors and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed in the section titled “Information Regarding Forward-Looking Statements.”

For the reasons set forth above, the Evans Board of Directors determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable and in the best interests of Evans and its shareholders, and unanimously adopted and approved the merger agreement and the transactions contemplated by it.

Accordingly, the Evans Board of Directors unanimously recommends that Evans shareholders vote “FOR” the merger proposal, “FOR” the compensation proposal, and “FOR” the adjournment proposal.

Vote Required for Approval

The affirmative vote of two-thirds of all outstanding shares entitled to vote on the proposal is required to approve the merger proposal. Abstentions will have the same effect as a vote against the merger proposal.

Recommendation of the Evans Board of Directors

THE EVANS BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE MERGER PROPOSAL.

Opinion of Piper Sandler & Co., Financial Advisor to Evans

Evans retained Piper Sandler to act as financial advisor to Evans’s Board of Directors in connection with Evans’s consideration of a possible business combination. Evans selected Piper Sandler to act as its financial advisor because Piper Sandler is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Piper Sandler is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

Piper Sandler acted as financial advisor to Evans’s Board of Directors in connection with the proposed merger and participated in certain of the negotiations leading to the execution of the merger agreement. At the September 9, 2024 meeting at which Evans’s Board of Directors considered the merger and the merger

agreement, Piper Sandler delivered to the Board of Directors its oral opinion, which was subsequently confirmed in writing on September 9, 2024, to the effect that, as of such date, the exchange ratio was fair to the holders of Evans common stock from a financial point of view. The full text of Piper Sandler’s opinion is attached as Annex B to this proxy statement/prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of Evans common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

Piper Sandler’s opinion was directed to the Board of Directors of Evans in connection with its consideration of the merger and the merger agreement and does not constitute a recommendation to any shareholder of Evans as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger and the merger agreement. Piper Sandler’s opinion was directed only to the fairness, from a financial point of view, of the exchange ratio to the holders of Evans common stock and did not address the underlying business decision of Evans to engage in the merger, the form or structure of the merger or any other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative transactions or business strategies that might exist for Evans or the effect of any other transaction in which Evans might engage. Piper Sandler also did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the merger by any officer, director, or employee of Evans or NBT or any class of such persons, if any, relative to the compensation to be received in the merger by any other shareholder. Piper Sandler’s opinion was approved by Piper Sandler’s fairness opinion committee.

In connection with its opinion, Piper Sandler reviewed and considered, among other things:

•	a draft of the merger agreement, dated September 3, 2024;

•	certain publicly available financial statements and other historical financial information of Evans and Evans Bank that Piper Sandler deemed relevant;

•	certain publicly available financial statements and other historical financial information of NBT and NBT Bank that Piper Sandler deemed relevant;

•

publicly available analyst consensus earnings per share estimates for Evans for the years ending December 31, 2024 and December 31, 2025 as well as an estimated long-term annual earnings per share growth rate for the years thereafter and estimated dividends per share for Evans for the years ending December 31, 2024 through December 31, 2028, as provided by the senior management of Evans;

•

internal financial projections for NBT for the year ending December 31, 2024 with a long-term annual balance sheet and net income growth rate for the years ending December 31, 2025 through December 31, 2028 and estimated dividends per share for NBT for the years ending December 31, 2024 through December 31, 2028, as provided by the senior management of NBT;

•

the pro forma financial impact of the merger on NBT based on certain assumptions relating to transaction expenses, cost savings and purchase accounting adjustments, as well as estimated net income for each of Evans and NBT for the year ending December 31, 2024 with an estimated long-term earnings growth rate for the years thereafter, as provided by the senior management of NBT;

•

the publicly reported historical price and trading activity for Evans common stock and NBT common stock, including a comparison of certain stock trading information for Evans common stock and NBT common stock and certain stock indices, as well as similar publicly available information for certain other companies, the securities of which are publicly traded;

•	a comparison of certain financial and market information for Evans and NBT with similar financial institutions for which information is publicly available;

•	the financial terms of certain recent business combinations in the bank and thrift industry (on nationwide basis), to the extent publicly available;

•	the current market environment generally and the banking environment in particular;

TABLE OF CONTENTS

•	such other information, financial studies, analyses and investigations and financial, economic and market criteria as Piper Sandler considered relevant.

Piper Sandler also discussed with certain members of the senior management of Evans and its representatives the business, financial condition, results of operations and prospects of Evans and held similar discussions with certain members of the management of NBT and its representatives regarding the business, financial condition, results of operations and prospects of NBT.

In performing its review, Piper Sandler relied upon the accuracy and completeness of all of the financial and other information that was available to and reviewed by Piper Sandler from public sources, that was provided to Piper Sandler by Evans or NBT or their respective representatives, or that was otherwise reviewed by Piper Sandler, and Piper Sandler assumed such accuracy and completeness for purposes of rendering its opinion without any independent verification or investigation. Piper Sandler relied on the assurances of the respective senior managements of Evans and NBT that they were not aware of any facts or circumstances that would have made any of such information inaccurate or misleading in any respect material to Piper Sandler’s analysis. Piper Sandler was not asked to and did not undertake an independent verification of any of such information and Piper Sandler did not assume any responsibility or liability for the accuracy or completeness thereof. Piper Sandler did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Evans or NBT, nor was Piper Sandler furnished with any such evaluations or appraisals. Piper Sandler rendered no opinion or evaluation on the collectability of any assets or the future performance of any loans of Evans or NBT or any of their respective subsidiaries. Piper Sandler did not make an independent evaluation of the adequacy of the allowance for loan losses of Evans or NBT, any of their respective subsidiaries, or of the combined entity after the merger, and Piper Sandler did not review any individual credit files relating to Evans or NBT or any of their respective subsidiaries. Piper Sandler assumed, with Evans’s consent, that the respective allowances for credit losses for Evans and NBT and their respective subsidiaries were adequate to cover such losses and would be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used publicly available analyst consensus earnings per share estimates for Evans for the years ending December 31, 2024 and December 31, 2025 as well as an estimated long-term annual earnings per share growth rate for the years thereafter and estimated dividends per share for Evans for the years ending December 31, 2024 through December 31, 2028, as provided by the senior management of Evans. In addition, Piper Sandler used certain internal financial projections for NBT for the year ending December 31, 2024 with a long-term annual balance sheet and net income growth rate for the years ending December 31, 2025 through December 31, 2028 and estimated dividends per share for NBT for the years ending December 31, 2024 through December 31, 2028, as provided by the senior management of NBT. Piper Sandler also received and used in its pro forma analyses certain assumptions relating to transaction expenses, cost savings and purchase accounting adjustments, as well as estimated net income for each of Evans and NBT for the year ending December 31, 2024 with an estimated long-term earnings growth rate for the years thereafter, as provided by the senior management of NBT. With respect to the foregoing information, the respective senior managements of Evans and NBT confirmed to Piper Sandler that such information reflected (or, in the case of the publicly available analyst estimates referred to above, were consistent with) the best currently available projections, estimates and judgments of those respective senior managements as to the future financial performance of Evans and NBT, respectively, and Piper Sandler assumed that the future financial results reflected in such information would be achieved. Piper Sandler expressed no opinion as to such information, or the assumptions on which such projections, estimates or judgements, or the assumptions on which they were based. Piper Sandler also assumed that there had been no material change in Evans’s or NBT’s assets, financial condition, results of operations, business or prospects since the date of the most recent financial statements made available to Piper Sandler. Piper Sandler assumed in all respects material to its analysis that Evans and NBT would remain as going concerns for all periods relevant to its analysis.

Piper Sandler also assumed, with Evans’s consent, that (i) each of the parties to the merger agreement would comply in all material respects with all material terms and conditions of the merger agreement and all related agreements required to effect the merger, that all of the representations and warranties contained in such agreements were true and correct in all material respects, that each of the parties to such agreements would perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements were not and would not be waived,

TABLE OF CONTENTS

(ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on Evans, NBT, the merger or any related transactions, and (iii) the merger and any related transactions would be consummated in accordance with the terms of the merger agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with Evans’s consent, Piper Sandler relied upon the advice that Evans received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the merger and the other transactions contemplated by the merger agreement. Piper Sandler expressed no opinion as to any such matters.

Piper Sandler’s opinion was necessarily based on financial, regulatory, economic, market and other conditions as in effect on, and the information made available to Piper Sandler as of, the date thereof. Events occurring after the date thereof could materially affect Piper Sandler’s opinion. Piper Sandler has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date thereof. Piper Sandler expressed no opinion as to the trading value of Evans common stock or NBT common stock at any time or what the value of NBT common stock would be once the shares are actually received by the holders of Evans common stock.

In rendering its opinion, Piper Sandler performed a variety of financial analyses. The summary below is not a complete description of all the analyses underlying Piper Sandler’s opinion or the presentation made by Piper Sandler to Evans’s Board of Directors, but is a summary of the material analyses performed and presented by Piper Sandler. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Piper Sandler believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Piper Sandler’s comparative analyses described below is identical to Evans or NBT and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or transaction values, as the case may be, of Evans and NBT and the companies to which they were compared. In arriving at its opinion, Piper Sandler did not attribute any particular weight to any analysis or factor that it considered. Rather, Piper Sandler made qualitative judgments as to the significance and relevance of each analysis and factor. Piper Sandler did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion, rather, Piper Sandler made its determination as to the fairness of the exchange ratio to the holders of Evans common stock on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

In performing its analyses, Piper Sandler also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of Evans, NBT, and Piper Sandler. The analyses performed by Piper Sandler are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. Piper Sandler prepared its analyses solely for purposes of rendering its opinion and provided such analyses to Evans’s Board of Directors at its September 9, 2024 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Piper Sandler’s analyses do not necessarily reflect the value of Evans common stock or NBT common stock or the prices at which Evans common stock or NBT common stock may be sold at any time. The analyses of Piper Sandler and its opinion were among a number of factors taken into consideration by Evans’s Board of Directors in making its determination to approve the merger agreement and the analyses described below should not be viewed as determinative of the decision of Evans’s Board of Directors with respect to the fairness of the exchange ratio.

Summary of Proposed Merger Consideration and Implied Transaction Metrics

Piper Sandler reviewed the financial terms of the proposed merger. Pursuant to the terms of the merger agreement, at the effective time of the merger each share of Evans common stock issued and outstanding immediately prior to the effective time of the transaction, except for certain shares as set forth in the merger agreement, shall be converted into the right to receive 0.91 of a share of NBT common stock. Piper Sandler calculated an aggregate implied transaction value of approximately $236.2 million and an implied per share transaction value of $42.11 consisting of the implied value of 5,525,838 shares of Evans common stock, 142,650 Evans stock options with a weighted average strike price of $32.79 and 49,984 Evans restricted stock units, based on the closing price of NBT common stock on September 6, 2024. Based upon financial information for Evans as of or for the last twelve months (“LTM”) ended June 30, 2024 and the closing price of Evans common stock on September 6, 2024, Piper Sandler calculated the following implied transaction metrics:


Transaction Price / Tangible Book Value Per Share			132%
Transaction Price / LTM Earnings Per Share			12.2x
Transaction Price / Core LTM Earnings Per Share¹			32.1x
Transaction Price / 2024 Estimated Consensus Earnings Per Share			24.5x
Tangible Book Premium / Core Deposits (CDs > $100K)²			3.7%
Tangible Book Premium / Core Deposits (CDs > $250K)³			3.4%
Premium to Evans Market Price as of September 6, 2024			18.3%

1	Adjusted for one-time items recorded in the fourth quarter of 2023: a $5.0 million pre-tax loss on sales of securities and a $20.1 million pre-tax gain on sale of insurance subsidiary; tax affected at 21.0% marginal tax rate

2	Core deposits equal to total deposits less CDs greater than $100,000

3	Core deposits equal to total deposits less CDs greater than $250,000

Net Present Value Analyses

Piper Sandler performed an analysis that estimated the net present value of a share of Evans common stock assuming Evans performed in accordance with publicly available analyst consensus earnings per share estimates for Evans for the years ending December 31, 2024 and December 31, 2025 as well as an estimated long-term annual earnings per share growth rate for the years thereafter and estimated dividends per share for Evans for the years ending December 31, 2024 through December 31, 2028, as provided by the senior management of Evans. To approximate the terminal value of a share of Evans common stock at September 6, 2024, Piper Sandler applied price to 2028 earnings multiples ranging from 9.0x to 14.0x and multiples of 2028 tangible book value ranging from 90% to 140%. The terminal values were then discounted to present values using different discount rates ranging from 9.0% to 13.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Evans common stock. As illustrated in the following tables, the

TABLE OF CONTENTS

analysis indicated an imputed range of values per share of Evans common stock of $19.12 to $31.81 when applying multiples of earnings and $23.50 to $39.82 when applying multiples of tangible book value.

Earnings Per Share Multiples


Discount Rate	9.0x	10.0x	11.0x	12.0x	13.0x	14.0x
9.0%	$22.14	$24.07	$26.01	$27.94	$29.88	$31.81
10.0%	$21.33	$23.18	$25.04	$26.90	$28.76	$30.61
11.0%	$20.55	$22.34	$24.12	$25.90	$27.69	$29.47
12.0%	$19.82	$21.53	$23.24	$24.96	$26.67	$28.38
13.0%	$19.12	$20.76	$22.41	$24.05	$25.70	$27.34

Tangible Book Value Per Share Multiples


Discount Rate	90%	100%	110%	120%	130%	140%
9.0%	$27.29	$29.80	$32.30	$34.81	$37.32	$39.82

13.0%	$23.50	$25.63	$27.76	$29.89	$32.02	$34.16

Piper Sandler also considered and discussed with Evans’s Board of Directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to earnings. To illustrate this impact, Piper Sandler performed a similar analysis, assuming Evans’s earnings varied from 20.0% above estimates to 20.0% below estimates. This analysis resulted in the following range of per share values for Evans common stock, applying the price to 2028 earnings multiples range of 9.0x to 14.0x referred to above and a discount rate of 10.87%.

Piper Sandler also performed an analysis that estimated the net present value per share of NBT common stock, assuming NBT performed in accordance with internal financial projections for NBT for the year ending December 31, 2024 with a long-term annual balance sheet and net income growth rate for the years ending December 31, 2025 through December 31, 2028 and estimated dividends per share for NBT for the years ending December 31, 2024 through December 31, 2028, as provided by the senior management of NBT. To approximate the terminal value of a share of NBT common stock at September 6, 2024 Piper Sandler applied price to 2028 earnings multiples ranging from 11.0x to 18.5x and multiples of 2028 tangible book value ranging from 150% to 225%. The terminal values were then discounted to present values using different discount rates ranging from 7.5% to 11.5%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of NBT common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of NBT common stock of $26.90 to $49.21 when applying multiples of earnings and $33.14 to $55.48 when applying multiples of tangible book value.

Piper Sandler also considered and discussed with Evans’s Board of Directors how this analysis would be affected by changes in the underlying assumptions, including variations with respect to earnings. To illustrate this impact, Piper Sandler performed a similar analysis assuming NBT’s earnings varied from 20.0% above projections to 20.0% below projections.

Piper Sandler noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

Pro Forma Transaction Analysis

Piper Sandler analyzed certain potential pro forma effects of the merger on NBT assuming the transaction closes first quarter of 2025. Piper Sandler utilized the following information and assumptions: (a) estimated net income for Evans for the year ending December 31, 2024 as well as an estimated long-term annual earnings growth rate for the years ending December 31, 2025 through December 31, 2028, as well as estimated dividends for Evans for the years ending December 31, 2024 through December 31, 2028 as provided by senior management of NBT, (b) estimated net income for NBT for the year ending December 31, 2024 as well as an estimated long-term annual earnings growth rate for the years ending December 31, 2025 through December 31, 2028, as confirmed by the senior management of NBT, as well as estimated dividends for NBT for the years ending December 31, 2024 through December 31, 2028 as provided by the senior management of NBT, and (c) certain assumptions related to transaction expenses, purchase accounting adjustments and cost savings, as provided by the senior management of NBT. The analysis indicated that the transaction could be accretive to NBT’s estimated earnings per share (excluding one-time transaction costs and expenses) in the years ending December 31, 2025 through December 31, 2028 and dilutive to NBT’s estimated tangible book value per share at close.

In connection with this analysis, Piper Sandler considered and discussed with the Evans Board of Directors how the analysis would be affected by changes in the underlying assumptions, including the impact of final purchase accounting adjustments determined at the closing of the transaction, and noted that the actual results achieved by the combined company may vary from projected results and the variations may be material.

Piper Sandler’s Relationship

Piper Sandler is acting as Evans’s financial advisor in connection with the transaction and will receive a fee for such services in an amount equal to 1.65% of the aggregate purchase price, which fee is contingent upon consummation of the merger. At the time of announcement of the transaction, Piper Sandler’s fee was approximately $3,897,300. Piper Sandler also received a $250,000 fee from Evans upon rendering its opinion, which opinion fee will be credited in full towards the transaction fee which will become payable to Piper Sandler

TABLE OF CONTENTS

upon closing of the transaction. Evans has also agreed to indemnify Piper Sandler against certain claims and liabilities arising out of Piper Sandler’s engagement and to reimburse Piper Sandler for certain of its out-of-pocket expenses incurred in connection with Piper Sandler’s engagement.

In the two years preceding the date of Piper Sandler’s opinion Piper Sandler provided certain other investment banking services to Evans. In summary, Piper Sandler acted as financial advisor to Evans in connection with the sale of its subsidiary, The Evans Agency, LLC, which transaction closed in November 2023 and for which Piper Sandler received approximately $2.3 million in advisory fees. Piper Sandler also provided certain investment banking services to NBT in the two years preceding the date of its opinion. In summary, Piper Sandler rendered an opinion to the board of directors of NBT in connection with NBT’s acquisition of Salisbury Bancorp, Inc. in December 2022 for which Piper Sandler received a fee of $500,000. In addition, in the ordinary course of Piper Sandler’s business as a broker-dealer, Piper Sandler may purchase securities from and sell securities to Evans, NBT and their respective affiliates. Piper Sandler may also actively trade the equity and debt securities of Evans, NBT and their respective affiliates for Piper Sandler’s account and for the accounts of Piper Sandler’s customers.

Certain Unaudited Prospective Financial Information

Evans does not as a matter of course make public long-term projections as to future revenues, earnings or other results due to, among other reasons, the uncertainty of the underlying assumptions and estimates. However, in connection with the merger, Evans’s management prepared and provided to the Evans Board of Directors in connection with its evaluation of the transaction, and to its financial advisor Piper Sandler, including in connection with Piper Sandler’s financial analyses described above under the section entitled “ —Opinion of Piper Sandler & Co., Financial Advisor to Evans,” certain unaudited prospective financial information regarding Evans’s operations described below (the “Evans Projections”). The below summary of the Evans Projections is included for the purpose of providing Evans shareholders access to certain nonpublic information that was furnished to certain parties in connection with the merger, and such information may not be appropriate for other purposes and is not included to influence the voting decision of any Evans shareholder.

Evans’s unaudited prospective financial information was not prepared with a view toward public disclosure, nor was it prepared with a view toward compliance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. No independent registered public accounting firm has audited, reviewed, examined, compiled or applied any procedures with respect to the prospective financial information and, accordingly, no independent public accounting firm has expressed any opinion or given any other form of assurance with respect thereto or its achievability. The inclusion of this unaudited prospective financial information should not be regarded as an indication that such information is predictive of actual future events or results and such information should not be relied upon as such, and readers of this proxy statement/prospectus are cautioned not to place undue reliance on the unaudited prospective financial information. The unaudited prospective financial information included in this proxy statement/prospectus has been prepared by, and is the responsibility of, Evans management.

While presented with numeric specificity, this unaudited prospective financial information was based on numerous variables and assumptions (including assumptions related to industry performance and general business, economic, market and financial conditions and additional matters specific to Evans’s business) that are inherently subjective and uncertain and are beyond the control of Evans’s management. Important factors that may affect actual results and cause this unaudited prospective financial information not to be achieved include, but are not limited to, risks and uncertainties relating to Evans’s business (including their ability to achieve strategic goals, objectives and targets over applicable periods), industry performance, general business and economic conditions and other factors described in the sections entitled “Information Regarding Forward-Looking Statements” and “Risk Factors.” This unaudited prospective financial information also reflects numerous variables, expectations and assumptions available at the time they were prepared as to certain business decisions that are subject to change. As a result, actual results may differ materially from those contained in this unaudited prospective financial information. Accordingly, there can be no assurance that the projected results summarized below will be realized.

None of Evans, NBT or their respective officers, trustees, directors, affiliates, advisors or other representatives can give you any assurance that actual results will not differ materially from this unaudited prospective financial information.

TABLE OF CONTENTS

EVANS UNDERTAKES NO OBLIGATION TO UPDATE OR OTHERWISE REVISE OR RECONCILE THIS UNAUDITED PROSPECTIVE FINANCIAL INFORMATION TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE THIS UNAUDITED PROSPECTIVE FINANCIAL INFORMATION WAS GENERATED OR TO REFLECT THE OCCURRENCE OF FUTURE EVENTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING SUCH INFORMATION ARE SHOWN TO BE IN ERROR. SINCE THE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION COVERS MULTIPLE YEARS, SUCH INFORMATION BY ITS NATURE BECOMES LESS PREDICTIVE WITH EACH SUCCESSIVE YEAR.

Evans has not made and makes no representation to NBT or any NBT shareholder, in the merger agreement or otherwise, concerning this unaudited prospective financial information or regarding Evans’s ultimate performance compared to the unaudited prospective financial information or that the projected results will be achieved. In light of the foregoing factors and the uncertainties inherent in the unaudited prospective financial information, Evans urges all Evans shareholders not to place undue reliance on such information.

The following information consists of publicly available consensus estimates relating to Evans and its related long-term earnings growth assumptions that senior management confirmed to Piper Sandler was consistent with the best then-currently available estimates and judgments of senior management: (i) estimated fiscal year 2024 Earnings Per Share of $1.72; (ii) estimated fiscal year 2025 Earnings Per Share of $2.30; and (iii) net income growth of 7.5% annually subsequent to fiscal year 2025. The Evans Projections were not updated to account for any circumstances or events occurring after the date they were initially prepared and therefore should not be relied on as predictive of actual future results.

Interests of Certain Evans Directors and Executive Officers in the Merger

In considering the recommendation of the Evans Board of Directors to vote for the merger proposal, Evans’s shareholders should know that the directors and executive officers of Evans have certain interests, including financial interests, in the merger that may be different from, or in addition to, the interests of Evans shareholders generally and that may create potential conflicts of interests. These interests are described below, to the extent they are material and are known to Evans. The Evans Board of Directors was aware of these interests and considered them, among other matters, in making its recommendation that Evans’s shareholders vote to approve the merger proposal.

The amounts presented in the following discussion do not reflect the impact of applicable withholding or other taxes.

Treatment of Stock Options

All unvested stock option grants shall vest immediately prior to the effective time so that all options outstanding at the effective time will automatically convert into the right to receive a lump sum cash payment equal to (i) the number of shares of Evans stock subject to such option, multiplied by (ii) the amount by which the per share consideration exceeds the per share exercise price of such option, less applicable taxes and other withholdings. The per share consideration means the product of (a) 0.91 and (b) the average of the daily closing prices during the regular session of NBT common stock as reported on NASDAQ for the five (5) consecutive trading days ending on the third business day immediately prior to the closing date, rounded to the nearest whole cent.

The following table sets forth the number of unvested Evans stock options held by each executive officer of Evans as of September 9, 2024, the date the merger agreement was executed, that are anticipated to vest in connection with the merger (and which excludes stock options that are scheduled to vest in the ordinary course in November 2024). The estimated value of the unvested stock options is based on (i) $39.25 (the average closing market price of Evans common stock over the first five (5) business days following the public announcement of the merger beginning on September 10, 2024) less the exercise price of each option, multiplied by (ii) the total number of unvested shares of Evans common stock subject to each option. No directors of Evans hold any stock options.

TABLE OF CONTENTS

Treatment of Restricted Stock Awards

Any vesting restrictions on each restricted share of Evans common stock outstanding immediately prior to the effective time of the merger will automatically and without any required action on the part of the holder thereof, fully vest and will be exchanged for the merger consideration within five (5) business days after the effective time, less applicable taxes required to be withheld and will be treated as issued and outstanding shares of Evans common stock.

The following table sets forth the number of unvested restricted shares of Evans common stock held by each director and each executive officer of Evans as of September 9, 2024, the date the merger agreement was executed, that are anticipated to vest in connection with the merger (and which excludes restricted stock awards that are scheduled to vest in the ordinary course in November 2024 and January 2025). The estimated value of the unvested restricted shares of Evans common stock is based on (i) $39.25 (the average closing market price of Evans common stock over the first five (5) business days following the public announcement of the merger beginning on September 10, 2024), multiplied by (ii) the total number of unvested restricted shares of Evans common stock subject to each award. Except for Mr. Nasca, no Evans director holds any restricted shares of Evans common stock that are anticipated to vest in connection with the merger (excluding restricted stock awards that are scheduled to vest in the ordinary course in January 2025).

Treatment of Performance-Based Restricted Stock Units

Each award of performance-based restricted stock units with respect to Evans common stock outstanding immediately prior to the effective time of the merger will become vested as to the number of shares that would vest based on the assumed achievement of the performance goals at the greater of the target level or actual achievement level (measured at the date of the effective time) and will be exchanged for the merger consideration within five (5) business days after the effective time, less applicable taxes required to be withheld.

The following table sets forth the number of unvested, unearned performance-based restricted stock units held by each executive officer of Evans as of September 9, 2024, the date the merger agreement was executed (other than those that were earned in the ordinary course pursuant to their terms for the performance period ending December 31, 2024), and anticipated to vest in connection with the merger, which are reflected at target level of achievement for performance-based restricted stock units granted in 2023 and 2024. The estimated aggregate value of the performance-based restricted stock unit award is based on (i) $39.25 (the average closing market price of Evans common stock over the first five (5) business days following the public announcement of the merger beginning on September 10, 2024), multiplied by (ii) the number of performance-based restricted stock units anticipated to vest in connection with the merger. No directors of Evans hold any performance-based restricted stock units.


Executive Officers	Target Number of Unvested, Unearned Performance-Based Restricted Stock Units (#)		Estimated Number of Performance-Based Restricted Stock Units Vesting (#)⁽¹⁾		Estimated Performance-Based Restricted Stock Units Value ($)⁽¹⁾
	2023	2024	2023	2024	2023	2024

The estimated number of performance-based restricted stock units vesting in connection with the merger is determined based upon the target number of unvested, unearned performance-based restricted stock units. The performance period for the 2023 awards commenced on January 1, 2023 and ends on December 31, 2025. The performance period for the 2024 awards commenced on January 1, 2024 and ends on December 31, 2026. The value number derived represents the estimated number of vested, earned performance-based restricted stock units, which is then multiplied by $39.25 to derive the estimated award value.

TABLE OF CONTENTS

Treatment of Time-Based Restricted Stock Units

Each award of time-based restricted stock units with respect to Evans common stock outstanding immediately prior to the effective time of the merger will automatically and without any required action on part of the holder thereof, fully vest and will be exchanged for the merger consideration within five (5) business days after the effective time, less applicable taxes required to be withheld and will be treated as issued and outstanding shares of Evans common stock for purposes of the merger agreement.

The following table sets forth the number of unvested time-based restricted stock units held by each executive officer of Evans as of September 9, 2024, the date the merger agreement was executed, that are anticipated to vest in connection with the merger (and which excludes restricted stock units that are scheduled to vest in the ordinary course in March 2025). The estimated aggregate value of the unvested time-based restricted stock unit award is based on (i) $39.25 (the average closing market price of Evans common stock over the first five (5) business days following the public announcement of the merger beginning on September 10, 2024), multiplied by (ii) the number of time-based restricted stock units anticipated to vest in connection with the merger. No directors of Evans hold any time-based restricted stock units.

Current Agreements and Benefit Plans with Evans’s Executive Officers

Executive Incentive Retirement Plan

Messrs. Connerton and Pawlak participate in the Evans Bank Executive Incentive Retirement Plan under which additional contributions will be owed due to the merger. Mr. Nasca does not participate in this plan.

Set forth below is the estimated value of the additional benefits that would be paid to each of the executive officers in connection with the merger.


Executive Officers			Estimated Value of Additional Benefit ($)
John B. Connerton			113,133
Kenneth D. Pawlak			137,804

Employment Agreement with David J. Nasca

David J. Nasca, President and Chief Executive Officer of Evans and Evans Bank, is party to an employment agreement that provides benefits in the event of an involuntary termination of employment without “cause” or a voluntary termination for “good reason” (as defined in the employment agreement), including the occurrence of such termination events following a change in control. In the event of a change in control followed by an involuntary termination of employment for reasons other than cause or voluntary termination of employment for good reason, Mr. Nasca is entitled to a lump sum cash payment equal to two (2) times: (i) his highest annual base salary rate at any time under the agreement, and (ii) the average annual incentive bonus paid to him during the three completed calendar years preceding the date of termination. Mr. Nasca is also entitled to life insurance coverage and non-taxable medical and dental coverage for one year substantially comparable to the coverage maintained for him by Evans Bank prior to his termination. In no event may any compensation payable under the employment agreement constitute an “excess parachute payment” under Section 280G of the Internal Revenue Code. For an estimate of the amount that would be payable to Mr. Nasca, see “— Potential Payments and Benefits to Evans’s Named Executive Officers in Connection with the Merger” below.

Change in Control Agreements with Other Executive Officers

Evans Bank has also entered into change in control agreements with John B. Connerton, Treasurer of Evans and Executive Vice President and Chief Financial Officer of Evans Bank, and Kenneth D. Pawlak, Executive Vice

TABLE OF CONTENTS

President and Chief Growth Officer of Evans Bank. The change in control agreements provide that, in the event the executive officer is involuntarily terminated on or after a change in control for reasons other than “cause” (as defined in the change in control agreement) or voluntarily terminates for “good reason” (as defined in the change in control agreement) on or after a change in control, the executive officer will be entitled to a lump sum cash payment equal to (i) two (2) times the highest rate of gross base salary earned by the executive during the prior twelve months (or the executive’s highest rate of gross base salary in effect immediately prior to the merger, if higher). In addition, the executive officer would be entitled to the continuation of current Evans Bank provided life insurance and non-taxable medical and health insurance coverage as set forth in the change in control agreement for twenty-four (24) months following the date of termination. In no event may any compensation payable under the change in control agreements constitute an “excess parachute payment” under Section 280G of the Internal Revenue Code. Such payment will be payable in a lump sum within 30 days following the executive officer’s date of termination of employment. For an estimate of the amount that would be payable to Messrs. Connerton and Pawlak, see “— Potential Payments and Benefits to Evans’s Named Executive Officers in Connection with the Merger” below.

Additional Benefits

In 2025, Evans employees, including executive officers, are expected to a receive a pro-rated 2025 cash bonus. The table below presents the components of the pro-rated potential benefit to be received by each of executive officers:


Executive Officers			Bonus ($)⁽¹⁾
David J. Nasca			87,429
John B. Connerton			34,682
Kenneth D. Pawlak			32,948

(1)	Represents a pro-rated cash bonus, calculated for this purpose assuming that the closing of the merger occurs as of May 31, 2025.

Also, certain executive officers may receive accelerated vesting of restricted stock awards, time-based and performance-based restricted stock units, and/or early payment of cash bonuses in calendar 2024 in order to mitigate the impact of any contractual 280G cutback provisions contained in any of their applicable agreements with Evans and/or Evans Bank if such cutbacks are projected to impact such executive.

Membership on the Boards of Directors of NBT and NBT Bank

Indemnification and Insurance of Directors and Officers

Pursuant to the merger agreement, NBT has agreed that it will indemnify, defend and hold harmless each present and former director and officer of Evans against any reasonable costs, expenses or fees (including reasonable attorneys’ fees), judgments, amounts paid in settlement, fines, penalties, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, and whether formal or informal, arising out of matters existing or occurring at or prior to the effective time of the merger, whether asserted or claimed prior to, at or after the effective time of the

TABLE OF CONTENTS

merger, arising in whole or part out of or pertaining to the fact that he or she was a director or officer of Evans or is or was serving at the request of Evans as a director, officer, employee or other agent of any other organization or in any capacity with respect to any employee benefit plan of Evans, including without limitation matters related to the negotiation, execution and performance of the merger agreement or any of the related transactions, to the fullest extent which such person would have been entitled to indemnification under Evans’s charter and bylaws prior to the effective date of the merger.

In addition, NBT has agreed to maintain a directors’ and officers’ liability insurance policy for six years after the effective time of the merger to cover the present officers and directors of Evans with respect to claims against such directors and officers arising from facts or events that occurred before the effective time of the merger; provided that, NBT is not obligated to pay more than 250% of Evans’s annual premiums for such coverage.

Potential Payments and Benefits to Evans’s Named Executive Officers in Connection with the Merger

This section sets forth the information required by Item 402(t) of the SEC’s Regulation S-K regarding compensation for each named executive officer of Evans that is based on, or otherwise relates to, the merger. This compensation is referred to as “golden parachute” compensation by the applicable SEC disclosure rules, and in this section such term is used to describe the merger-related compensation payable to Evans’s named executive officers. The “golden parachute” compensation payable to these individuals is subject to a non-binding advisory vote of holders of Evans common stock, as described in the section entitled “PROPOSAL 2—Merger-Related Executive Compensation.” The table below sets forth, for the purposes of this golden parachute disclosure, the amount of payments and benefits (on a pre-tax basis) that each of Evans’s named executive officers would receive, using the following assumptions:

•	the effective time of the merger will occur on May 31, 2025 (which is the assumed date solely for purposes of this golden parachute compensation disclosure);

•	the base salary rates for the named executive officers remain unchanged from those in place as of January 1, 2024;

•

for purposes of calculating the value of non-vested equity awards that will become vested as of the effective time of the merger, equity awards are those that are outstanding as of September 9, 2024, the date the merger agreement was executed (other than those that will vest in the ordinary course prior to May 31, 2025);

•	a price per share of Evans common stock of $39.25 (the average closing market price of Evans common stock over the first five (5) business days following the public announcement of the merger beginning on September 10, 2024); and

•	the employment of each named executive officer will be terminated without cause immediately following the effective time of the merger.

The calculations in the table below do not include amounts that Evans’s named executive officers were already entitled to receive or vested in as of the date of this proxy statement/prospectus. The calculations in the table also do not include certain compensation that may occur after the effective time of the merger to a named executive officer who continues in employment with NBT because such payments are contingent upon and will vest based on services to be provided following the closing of the merger. As a result of the foregoing assumptions, which may or may not actually occur or be accurate on the relevant date, including the assumptions described in the footnotes to the table, the actual amounts, if any, to be received by a named executive officer may materially differ from the amounts set forth below:

TABLE OF CONTENTS

(1)

Represents the estimated cash amount payable pursuant to the terms of Mr. Nasca’s employment agreement and Messrs. Connerton and Pawlak’s change in control agreements, each of which is considered a “double trigger” agreement because the amount is payable only if the named executive officer’s employment is terminated without “cause” or for “good reason” following a “change in control” of Evans (as such terms are defined in the respective severance or change in control agreement). For more information regarding these payments, see “Interests of Evans’s Directors and Executive Officers in the Merger – Current Agreements and Benefit Plans with Evans’s Executive Officers” above.

(2)

Represents the estimated value of the unvested stock options, restricted stock, unvested performance-based restricted stock unit awards (at target), and unvested time-based restricted stock units that are anticipated to become vested at the effective time, which are considered a “single trigger” benefit because under the merger agreement they are payable upon a change in control of Evans without regard to termination of employment. For more information regarding these payments, see “Interests of Evans’s Directors and Executive Officers in the Merger – Treatment of Stock Options” “Interests of Evans’s Directors and Executive Officers in the Merger – Treatment of Restricted Stock Awards” and “Interests of Evans’s Directors and Executive Officers in the Merger –Treatment of Performance-Based Restricted Stock Units” “Interests of Evans’s Directors and Executive Officers in the Merger –Treatment of Time-Based Restricted Stock Units” and “Interests of Evans’s Directors and Executive Officers in the Merger – Additional Benefits” above.

Represents the estimated value of continued medical, dental, disability and life insurance coverage pursuant to the terms of the relevant employment or change in control agreement, as applicable. These benefits are considered “double trigger” benefits because these benefits are provided only if the named executive officer’s employment is terminated without “cause” or for “good reason” following a “change in control” of Evans (as such terms are defined in the respective employment or change in control agreement). For more information regarding these payments, see “Interests of Evans’s Directors and Executive Officers in the Merger – Current Agreements and Benefit Plans with Evans’s Executive Officers” above.

Material U.S. Federal Income Tax Consequences of the Merger

The following discussion is a general summary of material U.S. federal income tax consequences of the merger to U.S. holders (as defined below) of Evans common stock that exchange their shares of Evans common stock for merger consideration. The U.S. federal income tax laws are complex, and the tax consequences of the merger may vary depending upon each shareholder’s individual circumstances or tax status. The following discussion is based on current provisions of the Code, existing temporary and final regulations under the Code and current administrative rulings and court decisions, all of which are subject to change, possibly on a retroactive basis. No attempt has been made to comment on all U.S. federal income tax consequences of the merger that may be relevant to Evans shareholders. The tax discussion set forth below is included for general information only. It is not intended to be, nor should it be construed to be, legal or tax advice to a particular Evans shareholder.

This discussion addresses only those Evans shareholders that hold their Evans common stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). Further, the following discussion may not apply to particular categories of holders of shares of Evans common stock subject to special treatment under the Code, such as insurance companies, financial institutions, broker-dealers, tax-exempt organizations, individual retirement and other tax-deferred accounts, banks, persons subject to the alternative minimum tax, persons who hold Evans capital stock as part of a straddle, hedging or conversion transaction, persons whose functional currency is other than the U.S. dollar, persons eligible for tax treaty benefits, foreign corporations, foreign partnerships and other foreign entities, individuals who are not citizens or residents of the United States and holders of stock options or holders whose shares were acquired pursuant to the exercise of an employee stock option or otherwise as compensation. In addition, this discussion does not address any alternative minimum tax or any state, local or non-U.S. tax consequences of the merger, nor does it address any tax consequences arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010.

You are urged to consult your tax advisors to determine the specific tax consequences of the merger, including any state, local or non-U.S. tax consequences of the merger.

TABLE OF CONTENTS

U.S. Holders

As used herein, a “U.S. holder” is a beneficial owner of Evans common stock who or that is, for U.S. federal income tax purposes:

•	an individual citizen or resident of the United States;

•	corporation (or other entity that is treated as a corporation for U.S. federal income tax purposes) that is created or organized (or treated as created or organized) in or under the laws of the United States or any state thereof or the District of Columbia;

•	an estate whose income is subject to U.S. federal income tax regardless of its source; or

•	a trust if (1) a U.S. court can exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) it has a valid election in place to be treated as a U.S. person.

Tax Consequences of the Merger Generally

NBT will receive an opinion from Hogan Lovells US LLP (“Hogan Lovells”) and Evans will receive an opinion from Luse Gorman, PC (“Luse Gorman”), each to be filed with the SEC and dated as of the same date as the registration statement of which this proxy statement/prospectus is a part, to the effect that the merger will qualify as a reorganization under Section 368(a) of the Code. The tax opinions to be received by NBT and Evans will be based on certain representations, covenants and assumptions, as set forth in certificates provided to Hogan Lovells and Luse Gorman by appropriate officers of NBT and Evans, all of which must continue to be true and accurate in all material respects as of the effective time of the merger. If any of the representations, covenants or assumptions relied upon by tax counsel are inaccurate, tax counsel may not be able to provide the closing date opinions, which are a condition to NBT and Evans’ respective obligations to complete the merger, or the tax consequences of the merger could differ from those described below. An opinion of counsel neither binds the Internal Revenue Service (the “IRS”) nor precludes the IRS or the courts from adopting a contrary position. Neither NBT nor Evans intends to obtain a ruling from the IRS regarding the tax consequences of the merger.

Based on the opinions that the merger will qualify as a reorganization under Section 368(a) of the Code, it is the opinion of Hogan Lovells and Luse Gorman that the material U.S. federal income tax consequences of the merger to U.S. holders of Evans common stock are as follows:

•

except with respect to cash received in lieu of a fractional share of NBT common stock, no gain or loss will be recognized by U.S. holders who exchange all of their Evans common stock solely for NBT common stock pursuant to the merger. A U.S. holder of Evans common stock who receives cash instead of a fractional share of NBT common stock will be treated as having received the fractional share pursuant to the merger and then as having exchanged the fractional share for cash in a redemption by NBT. As a result, such U.S. holder of Evans common stock will generally recognize gain or loss equal to the difference between the amount of cash received and the basis in his or her fractional share interest. This gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if, as of the effective time of the merger, the holding period for the shares (including the holding period of NBT common stock surrendered therefor) is greater than one (1) year. In general, long-term capital gains for non-corporate taxpayers may be eligible for a reduced rate of taxation. The deductibility of capital losses is subject to limitations;

•

the aggregate tax basis in the NBT common stock received by an Evans shareholder pursuant to the merger will equal that shareholder’s aggregate tax basis in the shares of Evans common stock being exchanged, reduced by any amount allocable to a fractional share of NBT common stock for which cash is received; and

•	the holding period of NBT common stock received by an Evans shareholder in the merger will include the holding period of the shares of Evans common stock being exchanged.

For purposes of the above discussion of the bases and holding periods for shares of Evans common stock and NBT common stock, Evans shareholders who acquired different blocks of Evans common stock at different times for different prices must calculate their basis, gains and losses, and holding periods separately for each identifiable block of such stock exchanged, converted, cancelled or received in the merger.

TABLE OF CONTENTS

Backup Withholding

Payments of cash to an Evans shareholder pursuant to the merger are subject to information reporting and may, under certain circumstances, be subject to backup withholding unless such shareholder provides NBT with its taxpayer identification number and otherwise complies with the backup withholding rules. Any amounts withheld from payments to an Evans shareholder under the backup withholding rules are not an additional tax and generally will be allowed as a refund or credit against the Evans shareholder’s federal income tax liability; provided that the Evans shareholder timely furnishes the required information to the IRS.

This summary does not address tax consequences that may vary with, or are contingent on, a U.S. holder’s individual circumstances. Moreover, it does not address any non-income tax or any non-U.S., state or local tax consequences of the merger. The tax consequences of the merger to you will depend upon the facts of your particular situation. Accordingly, we strongly urge you to consult with a tax advisor to determine the particular federal, state, local and non-U.S. income and other tax consequences to you of the merger.

Regulatory Approvals Required for the Merger

General

NBT and Evans have agreed to use all reasonable efforts to obtain all permits, consents, waivers, approvals and authorizations of all third parties and governmental authorities that are necessary to consummate the transactions contemplated by the merger agreement. This includes certain notices, approvals, waivers or consents from federal governmental authorities, including the Federal Reserve Bank of New York and the OCC. NBT and NBT Bank have filed or will file all required applications, notices and waiver requests to obtain the regulatory approvals and waivers necessary to consummate the merger. NBT and Evans cannot predict whether the required regulatory approvals will be obtained, when they will be received or whether such approvals will be subject to any conditions.

Office of the Comptroller of the Currency

To consummate the merger, NBT will seek the approval of the OCC under Section 18(c) of the Federal Deposit Insurance Act, as amended, which is commonly known as the Bank Merger Act, and the National Bank Consolidation and Merger Act, 12 USC 215 et seq. The OCC may not approve the merger if:

•	such transaction would result in a monopoly or would be in furtherance of any combination or conspiracy to monopolize or attempt to monopolize the business of banking in any part of the United States; or

•

the effect of such transaction, in any section of the country, may be to substantially lessen competition, or tend to create a monopoly, or in any manner restrain trade, unless the OCC finds that the anticompetitive effects of the merger are clearly outweighed in the public interest by the probable effect of the transaction in meeting the convenience and needs of the communities to be served.

In every case, the OCC is required to consider the financial and managerial resources and future prospects of the institutions concerned, the convenience and needs of the communities to be served, and the effectiveness of each insured depository institution involved in the proposed merger in combating money-laundering activities. Consideration of financial resources generally focuses on capital adequacy of the institutions involved. In assessing the convenience and needs of the community to be served, the OCC will consider such elements as the extent to which the proposed merger is likely to benefit the general public through higher lending limits, new or expanded services, reduced prices, increased convenience in utilizing the services and facilities of the resulting institution, or other means. The OCC, as required by the Community Reinvestment Act of 1977, as amended, will also note and consider the record of performance of NBT Bank and Evans Bank in meeting the credit needs of the entire community, including low and moderate-income neighborhoods. An unsatisfactory record may form the basis for denial or conditional approval of an application. Applicable regulations require publication of notice of an application for approval of the merger.

Federal Reserve Bank of New York

NBT will seek a waiver from the Federal Reserve Bank of New York (acting on delegated authority from the FRB) from application requirements associated with the merger pursuant to 12 CFR 225.12(d), which authorizes the Federal Reserve Bank of New York to waive application requirements associated with bank holding company

TABLE OF CONTENTS

mergers and a bank holding company acquiring a new subsidiary bank if the transaction involves a bank merger and certain other conditions are met, including that the bank merger will be approved under the Bank Merger Act. If the Federal Reserve Bank of New York does not provide this waiver, NBT will seek the requisite approval from the Federal Reserve Bank of New York to consummate the merger.

Accounting Treatment of the Merger

The merger will be accounted for using the acquisition method of accounting with NBT treated as the acquirer. Under this method of accounting, Evans’s assets and liabilities will be recorded by NBT at their respective fair values as of the closing date of the merger and added to those of NBT. Any excess of purchase price over the net fair values of Evans’s assets and liabilities will be recorded as goodwill. Any excess of the fair value of Evans’s net assets over the purchase price will be recognized in earnings by NBT on the closing date of the merger. Financial statements of NBT issued after the merger will reflect these values but will not be restated retroactively to reflect the historical financial position or results of operations of Evans prior to the merger. The results of operations of Evans will be included in the results of operations of NBT beginning on the effective date of the merger.

Dissenters’ Appraisal Rights

Evans shareholders are not entitled to appraisal or dissenters’ rights with respect to the merger.

Restrictions on Sales of Shares by Certain Affiliates

The shares of NBT common stock to be issued in the merger will be freely transferable under the Securities Act, except for shares issued to any shareholder who is an “affiliate” of NBT as defined by Rule 144 under the Securities Act. Affiliates consist of individuals or entities that control, are controlled by or are under common control with NBT and include the executive officers and directors of NBT and may include significant shareholders of NBT.

Stock Exchange Listing; Delisting and Deregistration of Evans Common Stock

The shares of NBT common stock to be issued in the merger will be listed for trading on NASDAQ and NBT will submit a notification form to NASDAQ. Following the consummation of the merger, shares of NBT common stock will continue to be traded on NASDAQ under the symbol “NBTB.” In addition, following the consummation of the merger, Evans common stock will be delisted from the NYSE, will be deregistered under the Exchange Act and will cease to be publicly traded.

Litigation Related to the Merger

Since the initial filing on October 24, 2024 of the registration statement of which this proxy statement/prospectus is a part, Evans has received Demand Letters from three purported Evans shareholders generally alleging that the registration statement filed with the SEC on October 24, 2024 omits material information in violation of the federal securities laws. The shareholders have demanded disclosure of certain additional information pertaining to certain financial projections for Evans, certain information with respect to Piper Sandler’s analysis, and other requested disclosures. Please see the section of this proxy statement/prospectus titled “Risk Factors—Risks Related to the Merger—Since the initial filing on October 24, 2024 of the registration statement of which this proxy statement/prospectus is a part, Evans and the Evans board of directors have received three Demand Letters from purported Evans shareholders, which could result in litigation related to the merger being filed against Evans, the Evans board of directors and/or NBT and the NBT board of directors, and additional demand letters may be received or litigation may be filed against them, which could prevent or delay the completion of the merger or otherwise negatively impact the business and operations of Evans and NBT” on page 19 of this proxy statement/prospectus for more information.

PROPOSAL 2— MERGER-RELATED EXECUTIVE COMPENSATION

As required by the federal securities laws, Evans is providing its shareholders with the opportunity to cast an advisory, non-binding vote on the compensation that may become payable to its named executive officers in connection with the completion of the merger, as disclosed in the section of this document captioned “PROPOSAL 1—The Merger—Interests of Evans’s Directors and Executive Officers in the Merger” and the related tables and narrative.

Your vote is requested. Evans believes that the compensation that may become payable to its named executive officers in connection with the completion of the merger is reasonable and the information regarding such compensation demonstrates that Evans’s executive compensation program was designed appropriately and structured to ensure the retention of talented executives and a strong alignment with the long-term interests of Evans shareholders. This vote is not intended to address any specific item of compensation, but rather the overall compensation that may become payable to Evans’s executive officers in connection with the merger. This vote is separate and independent from the vote of shareholders to approve the merger agreement. Evans asks that its shareholders vote “FOR” the following resolution:

RESOLVED, that the compensation that may become payable to Evans’s named executive officers in connection with the completion of the merger, as disclosed in the section captioned “PROPOSAL 1—The Merger—Interests of Evans’s Directors and Executive Officers in the Merger” and the related tables and narrative, is hereby approved.

Approval of this proposal is not a condition to the completion of the merger. In addition, this vote is advisory and, therefore, it will not be binding on Evans, nor will it overrule any prior decision of Evans or require the Evans Board of Directors (or any committee thereof) to take any action. However, the Evans Board of Directors values the opinions of Evans’s shareholders, and to the extent that there is any significant vote against the named executive officer compensation as disclosed in this proxy statement/prospectus, the Evans Board of Directors will consider shareholders’ concerns and will evaluate whether any actions are necessary to address those concerns. The Evans Board of Directors will consider the affirmative vote of the majority of the votes cast on the matter “FOR” the foregoing resolution as advisory approval of the compensation that may become payable to Evans’s named executive officers in connection with the completion of the merger.

Vote Required for Approval

The affirmative vote of a majority of the votes cast on the proposal is required to approve the compensation proposal. Abstentions will have no effect on the outcome of the compensation proposal.

Recommendation of the Evans Board of Directors

THE EVANS BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE COMPENSATION PROPOSAL.

TABLE OF CONTENTS

PROPOSAL 3— ADJOURNMENT OF THE SPECIAL MEETING

If there are not sufficient votes to constitute a quorum or to approve the merger agreement at the time of the special meeting, the merger agreement cannot be approved unless the special meeting is adjourned to a later date or dates to permit further solicitation of proxies. To allow proxies that have been received by Evans at the time of the special meeting to be voted for an adjournment, if deemed necessary, Evans has submitted the question of adjournment to its shareholders as a separate matter for their consideration. If it is deemed necessary to adjourn the special meeting, no notice of the adjourned meeting is required to be given to shareholders, other than an announcement at the meeting of the time and place to which the meeting is adjourned, as well as the means, if any, by which shareholders can be present and vote at the adjourned meeting through the use of communications equipment.

Vote Required for Approval

The affirmative vote of a majority of the votes cast on the proposal is required to approve the adjournment proposal. Abstentions will have no effect on the outcome of the adjournment proposal.

Recommendation of the Evans Board of Directors

THE EVANS BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE ADJOURNMENT PROPOSAL.

TABLE OF CONTENTS

THE MERGER AGREEMENT

This section of the proxy statement/prospectus describes the material terms of the merger agreement. The following summary is qualified in its entirety by reference to the complete text of the merger agreement, which is incorporated by reference into this proxy statement/prospectus and attached as Annex A to this proxy statement/prospectus. This summary may not contain all of the information about the merger agreement that may be important to you. You are urged to read the full text of the merger agreement. The merger agreement contains customary representations and warranties of NBT and Evans made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the agreement between NBT and Evans and are not intended to provide factual, business or financial information about NBT and Evans. Moreover, some of those representations and warranties may not be accurate or complete as of any specified date, may be subject to a contractual standard of materiality different from those generally applicable to shareholders or different from what a shareholder might view as material, may have been used for purposes of allocating risk between NBT and Evans rather than establishing matters as facts, may have been qualified by certain disclosures not reflected in the merger agreement that were made to the other party in connection with the negotiation of the merger agreement, and generally were solely for the benefit of the parties to that agreement.

Structure

Subject to the terms and conditions of the merger agreement, and in accordance with the Delaware General Corporation Law (“DGCL”) and the New York Business Corporation Law (“NYBCL”) and the regulations promulgated thereunder, at the completion of the merger, (i) Evans will merge with and into NBT and (ii) Evans Bank will merge with and into NBT Bank. NBT and NBT Bank will be the surviving entities in the merger and will continue their existences under the laws of the State of Delaware, in the case of NBT, and the laws of the United States, in the case of NBT Bank. Upon completion of the merger, the separate existences of Evans and Evans Bank will terminate.

The certificate of incorporation and the bylaws of NBT will remain as the certificate of incorporation and bylaws of NBT and the articles of association and the bylaws of NBT Bank will remain as the articles of association and bylaws of NBT Bank. See “Comparison of Stockholder Rights” beginning on page 75.

The merger agreement provides that NBT may, at any time prior to the effective time, change the method of effecting the business combination of NBT and Evans. However, no such change may (a) alter or change the merger consideration, (b) adversely affect the tax treatment of NBT or Evans in connection with the merger, or (c) be reasonably likely to materially impede or delay consummation of the transactions contemplated by the merger agreement.

Effective Time and Timing of Closing

The merger can be completed and become effective after the following steps are completed: (i) approval of the merger by the OCC (and expiration of the related statutory waiting period) and receipt of the Federal Reserve Bank of New York’s approval of the application waiver request (or approval of the merger by the Federal Reserve Bank of New York if the waiver request is denied), (ii) approval of the merger by the shareholders of Evans, and (iii) filing of all documents as may be required by applicable laws and regulations to consummate the merger, including a certificate of merger with the Delaware Department of State and the New York State Department of State. Subject to the satisfaction or waiver of all conditions to closing set forth in the merger agreement, the closing of the merger will occur as promptly as practicable after all of the conditions in the agreement have been satisfied, or if permissible, waived by the party entitled to the benefit of the same, or on such other date as NBT and Evans may mutually agree upon.

NBT and Evans anticipate that the merger will be completed in the second quarter of 2025. However, completion of the merger could be delayed if there is a delay in obtaining the required regulatory approvals or in satisfying any other conditions to the merger. There can be no assurances as to whether, or when, NBT and Evans will obtain the required approvals or complete the merger.

Boards of Directors of NBT and NBT Bank After the Merger

TABLE OF CONTENTS

2025 annual meeting proxy statement and the date of NBT’s 2025 annual meeting of stockholders, then the appointment of David J. Nasca (or, in the event of his unavailability, such other person as mutually agreed upon by Evans and NBT) to the boards of directors of NBT and NBT Bank will be effective immediately following their respective annual meetings of stockholders. Mr. Nasca must meet the qualifications for directors set forth in the bylaws of NBT and NBT Bank. Mr. Nasca will serve on the NBT and NBT Bank boards of directors until the next annual meeting following his appointment. If Mr. Nasca is appointed at any time other than immediately following the 2025 annual meeting of stockholders of NBT and NBT Bank, the NBT and NBT Bank boards of directors also will nominate Mr. Nasca for election at the first annual stockholder meeting following his appointment.

Consideration to be Received in the Merger

In the merger, each outstanding share of Evans common stock will be converted into the right to receive 0.91 shares of NBT common stock, plus cash in lieu of any fractional share.

No fractional shares of NBT common stock will be issued in connection with the merger. Instead, each Evans shareholder will receive an amount of cash, in lieu of any fractional share, based on the average per share closing price of NBT common stock on NASDAQ for the five consecutive trading days ending on the third business day immediately prior to the closing date of the merger, rounded to the nearest whole cent.

Exchange of Certificates; Dividends

Before the effective time of the merger, NBT will cause to be delivered to the exchange agent certificates, or at NBT’s option, evidence of shares in book-entry form, representing the shares of NBT common stock to be issued in the merger. In addition, NBT will deliver to the exchange agent an aggregate amount of cash consideration sufficient to pay the estimated amount of cash to be paid to Evans shareholders in lieu of fractional shares of NBT common stock. NBT has selected Equiniti Trust Company LLC to act as exchange agent in connection with the merger.

Promptly after the effective time of the merger, the exchange agent will mail to each Evans shareholder of record at the effective time of the merger a notice advising such holder of the effectiveness of the merger, including a form of letter of transmittal (in a form satisfactory to NBT and Evans) containing instructions for use in surrendering the shareholder’s Evans stock certificates. When such Evans shareholders deliver their Evans stock certificates to the exchange agent with a properly completed and duly executed letter of transmittal and any other required documents, their Evans stock certificates will be cancelled and in exchange, such Evans shareholders will receive:

•	an NBT stock certificate, or at the election of NBT, a statement reflecting shares issued in book-entry form, representing the number of whole shares of NBT common stock that they are entitled to receive under the merger agreement; and/or

•	a check representing the amount of cash that they are entitled to receive in lieu of any fractional shares.

Evans shareholders of record who hold Evans common stock in book-entry form will not be required to deliver a share certificate or an executed letter of transmittal. Promptly following the completion of the merger, shares of Evans common stock held in book-entry form will automatically be exchanged for the merger consideration in the form described above.

Evans shareholders are not entitled to receive any dividends or other distributions on NBT common stock with a record date after the effective time of the merger until they have surrendered their Evans stock certificates in exchange for an NBT stock certificate. After the surrender of their Evans stock certificates or the conversion of their book-entry shares, as applicable, Evans shareholders will be entitled to receive any dividend or other distribution, without interest, which had become payable with respect to their NBT common stock.

Treatment of Stock Options

TABLE OF CONTENTS

The per share consideration means the product of (a) 0.91 and (b) the average of the daily closing prices during the regular session of NBT common stock as reported on NASDAQ for the five (5) consecutive trading days ending on the third business day immediately prior to the closing date, rounded to the nearest whole cent.

Treatment of Restricted Stock Awards

Any vesting restrictions on each restricted share of Evans common stock subject to a substantial risk of forfeiture outstanding immediately prior to the effective time of the merger will automatically lapse and all vested restricted stock awards will be exchanged for the merger consideration and will be treated as issued and outstanding shares of Evans common stock.

Treatment of Performance-Based Restricted Stock Units

Each award of performance-based restricted stock units with respect to Evans common stock outstanding immediately prior to the effective time of the merger will become vested as to the number of shares that would vest based on the assumed achievement of the performance goals at the greater of the target level or actual achievement level (measured at the date of the effective time) and all performance-based restricted stock units will be exchanged for the merger consideration.

Treatment of Time-Based Restricted Stock Units

Each award of time-based restricted stock units with respect to Evans common stock outstanding immediately prior to the effective time of the merger will become vested as of the effective time and all vested restricted stock units will be exchanged for the merger consideration and will be treated as issued and outstanding shares of Evans common stock for purposes of the merger agreement.

Representations and Warranties

The merger agreement contains representations and warranties made by and to NBT and Evans. The statements embodied in those representations and warranties were made for purposes of the agreement between NBT and Evans and are subject to important qualifications and limitations agreed to by NBT and Evans in connection with negotiating the terms of the merger agreement. In addition, certain representations and warranties were made as of a specified date, may be subject to contractual standards of materiality different from what may be viewed as material to shareholders, or may have been used for the purpose of allocating risk between NBT and Evans rather than establishing matters as fact. For the foregoing reasons, you should not rely on the representations and warranties as statements of factual information. Third parties are not entitled to the benefits of the representations and warranties in the merger agreement.

Each of NBT, NBT Bank, Evans and Evans Bank has made representations and warranties to the other regarding, among other things:

•	due organization, good standing and authority;

•	capitalization;

TABLE OF CONTENTS

Evans Shareholder Meeting

Evans has agreed to use its best efforts to call, hold and convene a meeting of its shareholders within 50 days after the initial mailing of this proxy statement/prospectus to its shareholders to consider and vote on the approval of the merger agreement and any other matters required to be approved by its shareholders in order to consummate the merger in accordance with applicable law and the charter and bylaws of Evans.

Additionally, the Evans Board of Directors has agreed to recommend that its shareholders vote to approve the merger agreement and not withhold, withdraw, amend or modify such recommendation in any manner adverse to NBT or take any other action or make any other public statement inconsistent with such recommendation, except as and to the extent expressly permitted by merger agreement.

No Solicitation

Evans has agreed that neither it nor any of its respective directors, officers, employees, investment bankers, financial advisors, attorneys, accountants and other agents retained by Evans (which we refer to as Evans’s representatives) will, directly or indirectly:

•	solicit, initiate, induce or knowingly encourage or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an acquisition proposal;

•	participate in any discussions or negotiations regarding any acquisition proposal or furnish, or otherwise provide access to, any confidential or non-public information or data with respect to Evans or otherwise relating to an acquisition proposal; or

•	release any person from, waive any provision of, or fail to enforce any confidentiality agreement or standstill agreement to which Evans is a party.

Evans must immediately cease any existing discussions or negotiations with any person (other than NBT) with respect to any of the foregoing.

Under the merger agreement, an “acquisition proposal” means any proposal or offer with respect to any of the following (other than the transactions contemplated thereunder):

•	merger, consolidation, share exchange, business combination or other similar transactions;

•	sale, lease, exchange, mortgage, pledge, transfer or other disposition of assets and/or liabilities that constitute a substantial portion of the net revenues, net income or assets of Evans or Evans Bank in a single transaction or series of transactions;

•	tender offer or exchange offer for 25% or more of the outstanding shares of capital stock or the filing of a registration statement under the Securities Act in connection therewith; or

•	public announcement by any person of a proposal, plan or intention to do any of the foregoing or any agreement to engage in any of the foregoing.

If Evans receives a bona fide unsolicited written acquisition proposal prior to its shareholder meeting that did not result from a breach by Evans of any of the non-solicitation provisions in the merger agreement as discussed above, Evans may participate in discussions or negotiations regarding the unsolicited acquisition proposal or furnish the third party with, or otherwise afford access to the third party of, any information or data with respect to Evans or any of its subsidiaries or otherwise relating to the acquisition proposal if:

•

the Evans Board of Directors first determines in good faith, after consultation with its outside legal counsel and with respect to financial matters, its independent financial advisor, that such action would be required in order for directors of Evans to comply with their fiduciary duties under applicable law in response to an acquisition proposal that the Evans Board of Directors believes in good faith is a superior proposal;

•	Evans has provided NBT with notice of receipt of such acquisition proposal within one business day of such receipt; and

•

prior to furnishing or affording access to any information or data with respect to Evans or any of its subsidiaries or otherwise relating to an acquisition proposal, the third party enters into a confidentiality agreement with Evans containing terms no less favorable to Evans than those contained in its confidentiality agreement with NBT.

TABLE OF CONTENTS

A “superior proposal” means any bona fide written proposal made by a third party to acquire, directly or indirectly, including pursuant to a tender offer, exchange offer, merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction, for consideration consisting of cash and/or securities, more than 25% of the combined voting power of the shares of Evans common stock then outstanding or all or substantially all of the assets of Evans and otherwise (a) on terms which the Evans Board of Directors determines in good faith, after consultation with its financial advisor, to be more favorable from a financial point of view to the Evans’s shareholders than the transactions contemplated with NBT, and (b) that constitutes a transaction that, in the Evans Board of Directors’ good faith judgment, is reasonably likely to be consummated on the terms set forth, taking into account all legal, financial, regulatory and other aspects of such proposal.

Evans must deliver to NBT within 48 hours a new notice of each such superior proposal.

Employee Benefits

Following the closing date of the merger, NBT may, in its sole discretion, choose to maintain any or all of Evans’s benefit plans, and Evans and Evans Bank will cooperate with NBT in order to effect any plan terminations to be made as of the effective time of the merger in accordance with the terms of the applicable benefit plans. For the period commencing at the effective time of the merger and ending twelve (12) months after the effective time (or the applicable continuing employee’s earlier termination of employment), NBT will provide or cause to be provided to each Evans and Evans Bank employee who continues employment with NBT Bank (a “continuing employee”) (i) at least the same base salary or base rate of pay as provided to similarly situated employees of NBT or any subsidiary of NBT, and (ii) other benefits (other than severance or termination pay in order to avoid a duplication of benefits, if applicable) substantially comparable in the aggregate to the benefits provided to similarly situated employees of NBT or any subsidiary of NBT.

For any Evans benefit plan terminated for which there is a comparable NBT benefit plan of general applicability, NBT will take all commercially reasonable action so that continuing employees will be entitled to participate in such NBT benefit plan to the same extent as similarly-situated employees of NBT.

NBT will cause each NBT benefit plan in which continuing employees are eligible to participate to take into account for purposes of eligibility and vesting under the NBT benefit plans, but not for purposes of benefit accrual, the service of such employees with Evans or Evans Bank to the same extent as such service was credited for such purpose by Evans or Evans Bank. Such service, however, will not be recognized to the extent that such recognition would result in a duplication of benefits or retroactive application.

Following the closing date of the merger, NBT may amend or terminate any Evans benefit plan in accordance with its terms at any time.

Evans or Evans Bank, as applicable, will take all actions necessary to terminate its executive severance plan and change in control severance plan, and to adopt written resolutions to terminate such plans, and if requested by NBT in writing not less than forty-five (45) days prior to the closing, Evans or Evans Bank, as applicable, will take all actions necessary to cease contributions to and terminate each benefit plan that is intended to qualify as a 401(k) plan and to adopt written resolutions to terminate each such 401(k) plan; provided, however, that each such termination may be made contingent upon the consummation of the transactions contemplated by the merger agreement. In such event, NBT will take any and all actions as may be required to permit continuing employees to participate in an NBT benefit plan that is intended to qualify as a 401(k) plan immediately following the closing date and to permit continuing employees to roll over their account balances, including any participant loans, in the Evans 401(k) plan into the NBT 401(k) plan.

If an employee of Evans or Evans Bank becomes eligible to participate in a medical, dental, vision, prescription drug, or other health plan, disability plan or life insurance plan of NBT upon termination of such plan of Evans or Evans Bank, NBT will make all commercially reasonable efforts to cause each such plan to (a) waive any preexisting condition limitations to the extent such conditions are covered under the applicable NBT plan, (b) provide credit under any such plans for any deductible, co-payment and out-of-pocket expenses incurred by the employees and their beneficiaries during the portion of the calendar year prior to such participation, and (c) waive any waiting period limitation, actively-at-work requirement or evidence of insurability requirement which would otherwise be applicable to such employee on or after the effective time of the merger, in each case to the extent such employee satisfied any similar limitation or requirement under an analogous Evans benefit plan prior to the effective time of the merger.

TABLE OF CONTENTS

NBT agrees to honor all obligations under specified Evans employment agreements, change in control agreements, supplemental executive retirement plans, and similar arrangements. NBT agrees to assume and honor all specified Evans benefits plans.

NBT agrees to pay to each employee of Evans or Evans Bank that is not covered by a written employment or severance agreement and is terminated by NBT or any of its subsidiaries, without cause, within six (6) months following the effective time of the merger, a severance payment equal to two (2) weeks of his or her then current base salary multiplied by the number of total completed years of service with Evans or Evans Bank; provided, however, that for vice presidents and above, the severance payment will equal twenty-six (26) weeks of his or her base salary and for all other employees, the minimum severance payment will equal not less than twelve (12) weeks of his or her base salary and the maximum severance payment will not exceed twenty-six (26) weeks of his or her base salary; and provided further, that such employee enters into a release of claims in a form reasonably satisfactory to NBT and that such employee does not voluntarily leave employment with Evans or Evans Bank prior to the effective time of the merger.

NBT and Evans may provide a retention pool as mutually agreed by NBT and Evans to enable NBT and Evans to provide retention incentives to certain employees of Evans or Evans Bank who are not covered by a written employment agreement, the recipients and amounts to be mutually determined by NBT and Evans. Such designated employees will enter into retention agreements to be provided by Evans and reasonably acceptable to NBT.

Indemnification and Insurance

Indemnification

Under the merger agreement, NBT will indemnify and hold harmless each present and former director and officer of Evans and Evans Bank against any costs, expenses or fees (including reasonable attorneys’ fees), judgments, amounts paid in settlement, fines, penalties, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, for matters existing or occurring at or prior to the effective time of the merger, arising in whole or in part out of or pertaining to the fact that he or she was a director or officer of Evans and Evans Bank or is or was serving at the request of Evans or Evans Bank as a director, officer, employee or other agent of any other organization or in any capacity with respect to any employee benefit plan of Evans and Evans Bank, to the fullest extent which such indemnified party would be entitled under the NYBCL or the certificate of incorporation and the bylaws of Evans and Evans Bank as in effect of the date of the merger agreement.

Directors’ and Officers’ Insurance

The merger agreement requires NBT to use its reasonable best efforts to cause the directors and officers of Evans immediately prior to the effective time of the merger to be covered by Evans’s directors’ and officers’ liability insurance policy for a six-year period following the effective time of the merger with respect to acts or omissions occurring prior to the effective time committed by such directors and officers in their capacities as such. NBT will not be required to expend in any one year more than 250% of the current annual amount expended by Evans to maintain such insurance. If the current insurance policy requires NBT to expend more than this amount, NBT shall use reasonable best efforts to obtain as much comparable insurance as is available.

Voting Agreements

Each of the directors and executive officers of Evans have entered into voting agreements. In the voting agreements, these directors and executive officers agreed to vote, and granted NBT an irrevocable proxy and power of attorney to vote, all of his or her shares of Evans common stock, as applicable, in favor of the consummation of the merger or any of the transactions contemplated by the merger agreement and against any other acquisition proposal.

Except under limited circumstances, these directors and executive officers also agreed not to, directly or indirectly, sell, transfer, pledge, assign or otherwise dispose of, or enter into any contract, option, commitment or other arrangement or understanding with respect to the sale, transfer, pledge, assignment or other disposition of, any such shares. Each voting agreement terminates immediately upon the earlier of the adjournment of the meetings of shareholders of Evans called and held pursuant to merger agreement, or the termination of the merger agreement in accordance with its terms.

TABLE OF CONTENTS

As of the record date, these directors and executive officers held 263,149 shares of Evans common stock, which represented approximately 4.7% of the outstanding shares of Evans common stock. These directors and executive officers were not paid any additional consideration in connection with the execution of the voting agreement.

Additional Agreements

NBT and Evans have also agreed to use their reasonable best efforts in good faith to:

•	take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or advisable under applicable laws to consummate the merger and the transactions contemplated thereby as promptly as practicable; and

•	enable consummation of the transactions contemplated under the merger agreement, including the fulfillment of conditions set forth in the merger agreement, and cooperate fully with the other parties to the merger agreement to such end.

The merger agreement also contains covenants relating to cooperation in the preparation of this proxy statement/prospectus and additional agreements relating to, among other things, access to information and notice of certain matters.

Conditions to Complete the Merger

The obligations of NBT and Evans to consummate the merger are subject to the fulfillment of the following conditions:

•

NBT and Evans having obtained all regulatory approvals, and completed any requirements required by such regulatory approvals, required to consummate the transactions contemplated by the merger agreement and all related statutory waiting periods having expired or been terminated and no regulatory approvals contain any condition which the board of directors of either NBT or Evans determines in good faith would materially reduce the benefits of the merger such that one of the parties would not have entered into the merger agreement if known;

•	Evans and Evans Bank will have performed in all material respects all obligations required to be performed by it under the merger agreement at or prior to the closing date of the merger;

•

each of the representations and warranties of NBT set forth in the merger agreement will be true and correct as of the date of the merger agreement and as of the closing date of the merger, unless the failure of such representations and warranties to be true and correct, individually or in the aggregate, has not had, or would not reasonably be likely to have, a material adverse effect on NBT;

a decline in the trading price of a party’s common stock or the failure, in and of itself, to meet earnings projections or internal financial forecasts (it being understood that the underlying cause of such decline or failure may be taken into account in determining whether a material adverse effect has occurred);

by NBT or Evans if the other party materially breaches any of its representations, warranties, covenants or other agreements set forth in the merger agreement (provided that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained in the merger agreement), which breach is not cured within 30 days of written notice of the breach, or by its nature cannot be cured prior to the closing of the merger, and such breach would entitle the non-breaching party not to consummate the merger;

•	by NBT or Evans if the merger is not consummated by September 15, 2025, unless the failure to consummate the merger by such date is due to a material breach of the merger agreement by the terminating party;

•	by NBT if:

○	Evans materially breaches the non-solicitation provisions in the merger agreement;

○	the Evans Board of Directors fails to recommend approval of the merger agreement by the Evans shareholders, or withdraws, modifies or changes such recommendation in a manner adverse to NBT’s interests;

Any stockholder proposal pursuant to Rule 14a-8 under the Exchange Act intended to be presented at the 2025 annual meeting must be received at NBT’s executive offices no later than December 6, 2024 to be considered for inclusion in NBT’s 2025 proxy materials.

Evans 2025 Annual Shareholder Meeting and Shareholder Proposals

Evans does not anticipate holding a 2025 annual meeting of Evans shareholders if the merger is completed in the first half of 2025. However, if the merger is not completed within the expected time frame, or at all, Evans may hold an annual meeting of its shareholders in 2025. Evans must receive proposals that shareholders seek to include in the proxy statement for Evans’s next annual meeting by November 25, 2024. If the 2025 annual meeting of Evans shareholders is held on a date that is more than 30 calendar days from May 7, 2025, a shareholder proposal must be received by a reasonable time before Evans begins to print and mail its proxy solicitation materials for such annual meeting. Any shareholder proposals will be subject to the requirements of the proxy rules adopted by the SEC.

Evans’s bylaws provide that for a shareholder to make nominations for the election of directors or make proposals for business to be brought before a meeting of shareholders, such shareholder’s notice must be delivered or mailed to and received by the secretary of Evans not less than 90 days and not more than 120 days prior to the anniversary date of the immediately preceding annual meeting of shareholders; provided, however,

TABLE OF CONTENTS

that if the date of the annual meeting is advanced or delayed more than 30 days from the anniversary date of the preceding year’s annual meeting, notice by the shareholder to be timely must be so delivered not later than the close of business on the 10th day following the day on which public announcement of the date of such meeting is first made.

In addition to satisfying the foregoing advance notice requirements under Evans’s bylaws, to comply with the universal proxy rules under the Exchange Act, shareholders who intend to solicit proxies in support of director nominees other than Evans’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act, no later than March 8, 2025.

TABLE OF CONTENTS

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more shareholders sharing the same address by delivering a single proxy statement addressed to those shareholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for shareholders and cost savings for companies.

A number of brokers with account holders who are shareholders of Evans are expected to be “householding” the proxy materials. A single proxy statement/prospectus will be delivered to multiple shareholders sharing an address, unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate proxy statement and annual report, please notify your broker.

Shareholders who currently receive multiple copies of the proxy statement at their addresses and would like to request “householding” of their communications should contact their brokers.

WHEREAS, the NBT Board and the Evans Board have each (i) determined that this Agreement and the business combination and related transactions contemplated hereby are in the best interests of their respective entities and shareholders; (ii) determined that this Agreement and the transactions contemplated hereby are consistent with and in furtherance of their respective business strategies; and (iii) approved and declared advisable this Agreement and the transactions contemplated hereby;

WHEREAS, in accordance with the terms of this Agreement, Evans will merge with and into NBT, with NBT surviving (the “Merger”), and immediately thereafter, Evans Bank will merge with and into NBT Bank, with NBT Bank surviving (the “Bank Merger” and, together with the Merger, the “Transactions”);

WHEREAS, as a material inducement to NBT to enter into this Agreement, each of the directors and certain executive officers of Evans set forth on Evans Disclosure Schedule 6.02(c) has entered into a voting agreement with NBT dated as of the date hereof (a “Voting Agreement”), substantially in the form attached hereto as Exhibit A, pursuant to which each such director or executive officer has agreed, among other things, to vote all shares of Evans Stock (as defined herein) owned by such person in favor of the approval of this Agreement and the transactions contemplated hereby, upon the terms and subject to the conditions set forth in such agreement;

WHEREAS, for United States federal income tax purposes, the parties intend the Merger to qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended and the regulations and formal guidance issued thereunder (the “Code”), and that this Agreement be and hereby is adopted as a “plan of reorganization” within the meaning of Sections 354, 361 and 368 of the Code; and

WHEREAS, the parties desire to make certain representations, warranties and agreements in connection with the transactions described in this Agreement and to prescribe certain conditions thereto.

NOW, THEREFORE, in consideration of the mutual promises herein contained and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

Immediately thereafter, pursuant to the Plan of Bank Merger described in the following sentence, Evans Bank shall merge with and into NBT Bank, and NBT Bank shall be the surviving entity (hereinafter sometimes referred to as the “Surviving Bank”) and shall continue to be governed by the laws of the United States. As soon as practicable after the execution of this Agreement, NBT will cause NBT Bank to, and Evans will cause Evans Bank to, execute and deliver a Plan of Bank Merger substantially in the form attached to this Agreement as Exhibit B. As part of the Merger, shares of Evans Stock shall, at the Effective Time, be converted into the right to receive the Merger Consideration pursuant to the terms of Article II.

Section 1.02 Tax Consequences. It is intended that the Merger shall constitute a reorganization within the meaning of Section 368(a) of the Code, and that this Agreement shall constitute a “plan of reorganization” as that term is used in Sections 354, 361 and 368 of the Code. From and after the date of this Agreement and until the Closing, each party hereto shall use its reasonable best efforts to cause the Merger to qualify, and will not knowingly take any action, cause any action to be taken, fail to take any action or cause any action to fail to be taken, which action or failure to act would reasonably be expected to prevent the Merger from qualifying as a reorganization under Section 368(a) of the Code.

ARTICLE II

CONSIDERATION; EXCHANGE PROCEDURES

Section 2.01 Merger Consideration.

(a) Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of any Person:

(i) Each share of NBT Stock that is issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding following the Effective Time and shall be unchanged by the Merger.

(ii) Each share of Evans Stock issued and outstanding immediately prior to the Effective Time (other than shares of Evans Stock to be cancelled pursuant to Section 2.01(b)) shall become and be converted into the right to receive 0.91 (the “Exchange Ratio”) shares of NBT Stock (the “Merger Consideration”).

(b) At the Effective Time, all shares of Evans Stock that are owned by Evans as treasury stock and all shares of Evans Stock that are owned directly or indirectly by NBT or Evans, including any shares of Evans Stock held by NBT or Evans or any of their respective Subsidiaries in respect of a debt previously contracted, other than shares that are held by NBT or Evans, if any, in a fiduciary capacity, shall be canceled and shall cease to exist and no Merger Consideration shall be delivered in exchange therefor. All shares of NBT Stock that are owned by Evans shall become treasury stock of NBT.

Section 2.02 Rights as Shareholders; Stock Transfers. All shares of Evans Stock, when converted as provided in Section 2.01(a)(ii), shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each certificate previously evidencing such shares of Evans Stock (each, a “Certificate”, it being understood that any reference herein to “Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of shares of Evans Stock) shall thereafter represent only the right to receive for each such share of Evans Stock, the Merger Consideration and, if applicable, any cash in lieu of fractional shares of NBT Stock in accordance with Section 2.03(f). At the Effective Time, holders of Evans Stock shall cease to be, and shall have no rights as, shareholders of Evans other than the right to receive the Merger Consideration and cash in lieu of fractional shares of NBT Stock as provided under this Article II. After the Effective Time, there shall be no transfers on the stock transfer books of Evans of shares of Evans Stock.

Section 2.03 Exchange Procedures.

(a) If any portion of the Merger Consideration is to be paid to a Person other than the Person in whose name a Certificate surrendered pursuant to Section 2.03(c) is registered, it shall be a condition to such payment that such Certificate shall be properly endorsed or otherwise be in proper form for transfer, as applicable, and the Person requesting such payment shall inform the Exchange Agent, pursuant to an agreement entered into prior to Closing, whether any transfer or other similar Taxes are required as a result of such payment to a Person other than the registered holder of such Certificate, or establish to the reasonable satisfaction of the Exchange Agent that such Taxes are not payable. If such transfer or other similar Taxes are payable pursuant to the preceding sentence, then the Exchange Agent shall withhold and deduct from the Merger Consideration (including cash in lieu of fractional shares of NBT Stock) otherwise payable pursuant to this Agreement to the designated Person other than the registered holder, such amounts as the Exchange Agent determines are necessary based on the information supplied by the registered holder. The Exchange Agent (or, subsequent to the twelve (12) month anniversary of the Effective Time, NBT) shall be entitled to deduct and withhold from the Merger Consideration (including cash in lieu of fractional shares of NBT Stock) otherwise payable pursuant to this Agreement to any holder of Evans Stock such amounts as the Exchange Agent or NBT, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign Tax law, with respect to the making of such payment. To the extent that any amounts are withheld by the Exchange Agent or NBT, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Evans Stock in respect of whom such deduction and withholding was made by the Exchange Agent or NBT, as the case may be.

(b) At least one (1) business day prior to the Effective Time, NBT shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of Evans Stock pursuant to this Article II (i) certificates, or at NBT’s option, evidence of shares in book-entry form, representing the shares of NBT Stock,

TABLE OF CONTENTS

sufficient to pay the aggregate Merger Consideration required pursuant to this Article II, and (ii) an aggregate amount of cash sufficient to pay the estimated amount of cash to be paid in lieu of fractional shares of NBT Stock, each to be given to the holders of Evans Stock in exchange for Certificates pursuant to this Article II. Until the twelve (12) month anniversary of the Effective Time, NBT shall make available on a timely basis or cause to be made available to the Exchange Agent the following: (i) certificates, or at NBT’s option, evidence of shares in book-entry form, representing the shares of NBT Stock, sufficient to pay the aggregate Merger Consideration required pursuant to this Article II, and (ii) an aggregate amount of cash sufficient to pay the estimated amount of cash to be paid in lieu of fractional shares of NBT Stock, each to be given to the holders of Evans Stock in exchange for Certificates pursuant to this Article II. Upon such twelve (12) month anniversary, any such cash or certificates remaining in the possession of the Exchange Agent, together with any earnings in respect thereof, shall be delivered to NBT. Any holder of Certificates who has not theretofore exchanged his or her Certificates for the Merger Consideration pursuant to this Article II or who has not theretofore submitted a letter of transmittal, if required, shall thereafter be entitled to look exclusively to NBT, and only as a general creditor thereof, for the Merger Consideration, as applicable, to which he or she may be entitled upon exchange of such Certificates pursuant to this Article II. If outstanding Certificates are not surrendered, or the payment for the Certificates is not claimed prior to the date on which such payment would otherwise escheat to or become the property of any Governmental Authority, the unclaimed items shall, to the extent permitted by abandoned property and any other applicable law, become the property of NBT (and to the extent not in its possession shall be delivered to it), free and clear of all Liens of any Person previously entitled to such property. Neither the Exchange Agent nor any of the parties hereto shall be liable to any holder of Evans Stock represented by any Certificate for any consideration paid to a public official pursuant to applicable abandoned property, escheat or similar laws. NBT and the Exchange Agent shall be entitled to rely upon the stock transfer books of Evans to establish the identity of those Persons entitled to receive the Merger Consideration, which books shall be conclusive with respect thereto.

(c) Promptly after the Effective Time, NBT shall cause the Exchange Agent to mail or deliver to each Person who was, immediately prior to the Effective Time, a holder of record of Evans Stock a notice advising such holders of the effectiveness of the Merger, including a letter of transmittal in a form reasonably satisfactory to NBT and Evans containing instructions for use in effecting the surrender of Certificates in exchange for the Merger Consideration which shall specify that delivery shall be effected, and risk of loss and title to Certificates shall pass, only upon with respect to shares evidenced by Certificates, proper delivery to the Exchange Agent of such Certificates and the transmittal materials, duly, completely and validly executed in accordance with the instructions thereto. Upon surrender to the Exchange Agent of a Certificate for cancellation together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, the holder of such Certificate shall promptly be provided in exchange therefor, but in no event later than five (5) Business Days after due surrender, (x) a certificate, or at the election of NBT, a statement reflecting shares issued in book-entry form, representing the number of whole shares of NBT Stock that such holder is entitled pursuant to this Article II, and (y) a check in the amount equal to the sum of (A) any cash in lieu of fractional shares pursuant to Section 2.03(f) and (B) any dividends or other distributions that such holder is entitled pursuant to Section 2.03(e), and the Certificate so surrendered shall forthwith be canceled. No interest will accrue or be paid with respect to any property to be delivered upon surrender of Certificates.

(d) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by NBT or the Exchange Agent, the posting by such Person of a bond in customary amount as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, NBT shall cause the Exchange Agent to issue the Merger Consideration deliverable to such Person, and any cash, unpaid dividends or other distributions that would be payable or deliverable to such Person, in respect of the shares of Evans Stock represented by such lost, stolen or destroyed Certificate.

(e) No dividends or other distributions with respect to NBT Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of NBT Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to subsection (f) below, and all such dividends, other distributions and cash in lieu of fractional shares of NBT Stock shall be paid by NBT to the Exchange Agent, in each case until the surrender of such Certificate in accordance with this Section 2.03. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate there shall be paid to the holder of the whole shares of NBT Stock

A-5

TABLE OF CONTENTS

issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of NBT Stock and the amount of any cash payable in lieu of a fractional share of NBT Stock to which such holder is entitled pursuant to subsection (f), and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of NBT Stock. NBT shall make available to the Exchange Agent cash for these purposes, if necessary.

(f) Notwithstanding any other provision hereof, no fractional shares of NBT Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger; no dividend or distribution by NBT shall relate to such fractional share interests; and such fractional share interests will not entitle the owner thereof to vote or to any other rights as a stockholder of NBT. In lieu of any such fractional shares, NBT shall pay to each holder of a fractional share of NBT Stock an amount of cash (without interest) determined by multiplying the fractional share interest to which such holder would otherwise be entitled by the average of the daily closing prices during the regular session of NBT Stock as reported on NASDAQ for the five (5) consecutive trading days ending on the third Business Day immediately prior to the Closing Date, rounded to the nearest whole cent (the “NBT Measurement Price”).

(g) NBT, in the exercise of its reasonable discretion, shall have the right to make all determinations, not inconsistent with the terms of this Agreement, governing (A) the issuance and delivery of shares of NBT Stock into which shares of Evans Stock are converted in the Merger and (B) the method of payment of cash in lieu of fractional shares of NBT Stock.

Section 2.04 Anti-Dilution Provisions. In the event NBT or Evans changes (or establishes a record date for changing) the number of, or provides for the exchange of, shares of NBT Stock or Evans Stock issued and outstanding prior to the Effective Time as a result of a stock split, stock dividend, recapitalization, reclassification, or similar transaction with respect to the outstanding NBT Stock or Evans Stock and the record date therefor shall be prior to the Effective Time, the Exchange Ratio shall be proportionately and appropriately adjusted; provided, however, that, for the avoidance of doubt, no such adjustment shall be made with regard to NBT Stock if (a) NBT issues additional shares of NBT Stock and receives consideration for such shares in a bona fide third party transaction, (b) NBT issues additional shares of NBT Stock under the NBT Bancorp Inc. 2024 Omnibus Incentive Plan, or (c) NBT issues employee, director or other key service provider stock grants or similar equity awards or shares of NBT Stock upon the exercise or settlement thereof.

Section 2.05 Reservation of Shares. Effective upon the date of this Agreement, NBT shall reserve for issuance a sufficient number of shares of NBT Stock for the purpose of issuing shares of NBT Stock to Evans shareholders in accordance with this Article II.

Section 2.06 Listing of Additional Shares Prior to the Effective Time, NBT shall notify NASDAQ of the additional shares of NBT Stock to be issued by NBT in exchange for the shares of Evans Stock.

Section 2.07 Treatment of Equity Awards.

(a) Treatment of Stock Options. At the Effective Time, each option to purchase a share of Evans Stock (“Evans Option”), whether vested or unvested, that is outstanding as of immediately prior to the Effective Time, shall, without any required action on the part of the holder thereof, be cancelled and automatically converted into the right to receive a lump sum cash payment, payable within ten days following the Effective Time, from Evans or Evans Bank, as applicable, equal to (i) the number of shares of Evans Stock subject to such Evans Option at the Effective Time, multiplied by (ii) the amount by which the Per Share Consideration exceeds the per share exercise price of such Evans Option, less applicable taxes and other withholdings and without interest. For the avoidance of doubt, if the per share exercise price for an Evans Option is equal to or in excess of the Per Share Consideration, such Evans Option shall be cancelled at the Effective Time in exchange for no consideration. For the avoidance of doubt, NBT shall not assume any Evans Options.

(b) Treatment of Restricted Stock Awards. Immediately prior to the Effective Time, any vesting or other forfeiture restrictions on each share of Evans Stock subject to a substantial risk of forfeiture (“Evans Restricted Stock”) outstanding as of immediately prior to the Effective Time shall, automatically and without any required action on the part of the holder thereof, accelerate in full and fully vest and shall be converted into, and become

exchanged for the Merger Consideration within five (5) business days after the Effective Time, less applicable Taxes required to be withheld, if any, with respect to such vesting, and shall be treated as an issued and outstanding share of Evans Stock for the purposes of this Agreement. For the avoidance of doubt, NBT shall not assume any Evans Restricted Stock.

(c) Treatment of Performance-Based Restricted Stock Units. Immediately prior to the Effective Time, each award of performance-based restricted stock units with respect to Evans Stock (“Evans Performance-Based RSUs”) outstanding as of immediately prior to the Effective Time (i) shall become vested as to the number of shares of Evans Stock subject to such Evans Performance-Based RSU award that would vest based on the greater of target level achievement of all performance goals (without application of any modifier) or actual level of achievement of all relevant performance goals(rounded to the nearest whole share), and (ii) shall be converted into, and become exchanged for the Merger Consideration within five (5) business days after the Effective Time, less applicable Taxes required to be withheld, if any, with respect to such vesting. For the avoidance of doubt, NBT shall not assume any Evans Performance-Based RSUs.

(d) Treatment of Time-Based Restricted Stock Units. Immediately prior to the Effective Time, each award of time-based restricted stock units with respect to Evans Stock (“Evans Time-Based RSUs”) outstanding as of immediately prior to the Effective Time shall, automatically and without any required action on the part of the holder thereof, accelerate in full and fully vest and shall be converted into, and become exchanged for the Merger Consideration within five (5) business days after the Effective Time, less applicable Taxes required to be withheld, if any, with respect to such vesting, and shall be treated as an issued and outstanding share of Evans Stock for the purposes of this Agreement. For the avoidance of doubt, NBT shall not assume any Evans Time-Based RSUs.

(e) Prior to the Effective Time, Evans shall take all actions that may be necessary or required (under any Evans Equity Plan, any applicable law, the applicable award agreements or otherwise) (i) to effectuate the provisions of this Section 2.07, (ii) to terminate each Evans Equity Plan as of the Effective Time without any further obligation or liability, and (iii) to ensure that, from and after the Effective Time, holders of Evans Options, Evans Restricted Stock, and Evans RSUs shall have no rights with respect to thereto other than those rights specifically provided in this Section 2.07, if any.

possible disclosure from the third party to whom it owes an obligation of confidentiality. All requests made pursuant to this Section 5.10 will be directed to an executive officer of Evans or such Person or Persons as may be designated by Evans.

(b) Notwithstanding Section 5.11(a), prior to the Evans Meeting, Evans may take any of the actions described in clause (ii) of Section 5.11(a) if, but only if, (i) Evans has received a bona fide unsolicited written Acquisition Proposal that did not result from a breach of this Section 5.11; (ii) the Evans Board determines in good faith, (A) after consultation with its outside legal counsel and, with respect to financial matters, its independent financial advisor, that such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (B) after consultation with its outside legal counsel, and with respect to financial matters, its financial advisors, determines in good faith that it is required to take such actions to comply with its fiduciary duties under applicable law; (iii) Evans has provided NBT with at least 48 hours’ prior notice of such determination; and (iv) prior to furnishing or affording access to any information or data with respect to Evans or otherwise relating to an Acquisition Proposal, Evans receives from such Person a confidentiality agreement with terms not materially less favorable to Evans than those contained in the Confidentiality Agreement. In addition, if Evans receives an Acquisition Proposal that constitutes or is reasonably expected to result in a Superior Proposal and Evans has not breached any of the covenants set forth in this Section 5.11, then Evans, or any Evans Representative may, with the prior approval of the Evans Board at a duly called meeting, contact the Person who has submitted (and not withdrawn) such Acquisition Proposal, or any of such Person’s representatives, solely (x) to clarify the terms and conditions of such Acquisition Proposal and (y) if such Acquisition Proposal initially is made orally, to direct such Person to submit the Acquisition Proposal to Evans confidentially in writing. Evans shall promptly provide to NBT any non-public information regarding Evans provided to any other Person which was not previously provided to NBT, such additional information to be provided no later than the date of provision of such information to such other party.

(c) Evans shall promptly (and in any event orally within one Business Day and in writing within two Business Days) notify NBT if any inquiries, proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, Evans or the Evans Representatives, in each case in connection with any Acquisition Proposal, and such notice shall indicate the name of the Person initiating such discussions or negotiations or making such inquiry, proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such inquiry, proposal, offer, information request, negotiations or discussion, providing copies of such materials (including e-mails or other electronic communications)). Evans agrees that it shall keep NBT informed, on a reasonably current basis (and in any event within 24 hours), of the status and terms of any material developments with respect to such inquiry, proposal, offer, information request, negotiations or discussions (including, in each case, any amendments or modifications thereto). Evans shall provide NBT with at least 48 hours’ prior notice of any meeting of the Evans Board at which the Evans Board is reasonably expected to consider any Acquisition Proposal.

(e) Notwithstanding anything to the contrary set forth in this Agreement, prior to the Evans Meeting, the Evans Board may withdraw, qualify, amend or modify the Evans Recommendation in connection therewith (a “Evans Subsequent Determination”) and/or terminate this Agreement pursuant to Section 7.01(g)(ii) after the fourth Business Day following NBT’s receipt of a written notice (the “Notice of Superior Proposal”) from Evans advising NBT that the Evans Board intends to determine that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of this Section 5.11) constitutes a Superior Proposal if, but only if, (i) the Evans Board has reasonably determined in good faith, after consultation with outside legal counsel, that it is required to take such actions to comply with its fiduciary duties under applicable law, (ii) during the three Business Day period after receipt of the Notice of Superior Proposal by NBT (the “Notice Period”), Evans and the Evans Board shall have cooperated and negotiated in good faith with NBT to make such adjustments, modifications or amendments to the terms and conditions of this Agreement as would enable Evans to proceed with the Evans Recommendation without an Evans Subsequent Determination; provided, however, that NBT shall not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement, and (iii) at the end of the Notice Period, after taking into account any such adjusted, modified or amended terms as may have been proposed by NBT since its receipt of such Notice of Superior Proposal, the Evans Board in good faith makes the determination (A) in clause (i) of this Section 5.11(e) and (B) that such Acquisition Proposal constitutes a Superior Proposal. In the event of any material revisions to the Superior Proposal, Evans shall be required to deliver a new Notice of Superior Proposal to NBT and again comply with the requirements of this Section 5.11(e), except that the Notice Period shall be reduced to two Business Days.

Prior to the Effective Date, Evans shall, consistent with GAAP and applicable banking laws and regulations, modify or change its loan, OREO, accrual, reserve, tax, litigation and real estate valuation policies and practices (including loan classifications and levels of reserves) so as to be applied on a basis that is consistent with that of NBT; provided, however, that Evans shall not be obligated to take any action pursuant to this Section 5.12 unless and until all Regulatory Approvals have been obtained and NBT acknowledges in writing, and Evans is satisfied, that all conditions to Evans’s obligation to consummate the Merger have been satisfied and that NBT shall consummate the Merger in accordance with the terms of this Agreement, and further provided that in any event, no accrual or reserve made by Evans pursuant to this Section 5.12 or the consequences resulting therefrom shall constitute or be deemed to be a breach, violation of or failure to satisfy any representation, warranty, covenant, agreement, condition or other provision of this Agreement or otherwise be considered in determining whether any such breach, violation or failure to satisfy shall have occurred. The recording of any such adjustments shall not be deemed to imply any misstatement of previously furnished financial statements or information and shall not be construed as concurrence of Evans or its management with any such adjustments, nor any admission that the previously furnished financial statements or information did not fully comply in all respects with GAAP or regulatory requirements.

Section 5.13 Indemnification.

(a) From and after the Effective Time, NBT (the “Indemnifying Party”) shall indemnify and hold harmless each present and former director and officer of Evans or Evans Bank, as applicable, determined as of the Effective Time (the “Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, amounts paid in settlement, fines, penalties, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, and whether formal or informal (each, a “Proceeding”) arising out of matters existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, arising in whole or in part out of or pertaining to the fact that he or she was a director or officer of Evans or Evans Bank or is or was serving at the request of Evans or Evans Bank as a director, officer, employee or other agent of any other organization or in any capacity with respect to any employee benefit plan of Evans or Evans Bank, including without limitation matters related to the negotiation, execution and performance of this Agreement or any of the transactions contemplated hereby, to the fullest extent which such Indemnified Parties would be entitled under the NYBCL or the Certificate of Incorporation, as amended, and the Amended and Restated Bylaws of Evans or Evans Bank as in effect on the date hereof (subject to change as required by law), including with respect to the advancement of expenses. Notwithstanding any other provision of this Section 5.13, the Indemnifying Party shall advance all reasonable costs, expenses and fees (including reasonable attorneys’ fees) incurred by or on behalf of an Indemnified Party in connection with any Proceeding within thirty (30) days after the receipt by the Indemnifying Party of a statement or statements from the Indemnified Party requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall be made in good faith and shall reasonably evidence the costs, expenses and fees incurred by the Indemnified Party (which shall include invoices in connection with such costs, fees and expenses but, in the case of invoices in connection with legal services, any references to legal work performed or to expenditure made that would cause the Indemnified Party to waive any privilege or protection accorded by applicable law shall not be included with the invoice), and shall include or be preceded or accompanied by a written undertaking by or on behalf of the Indemnified Party to repay any costs, expenses or fees advanced if it shall ultimately be determined that the Indemnified Party is not entitled to be indemnified against such costs, expenses or fees. Any advances and undertakings to repay pursuant to this Section 5.13 shall be unsecured and interest free and made without regard to the Indemnified Party’s ability to repay such advances or ultimate entitlement to indemnification.

(b) Any Indemnified Party wishing to claim indemnification under this Section 5.13, upon learning of any such Proceeding, shall promptly notify the Indemnifying Party, but the failure to so notify shall not relieve the Indemnifying Party of any liability it may have to such Indemnified Party except to the extent that such failure does actually prejudice the Indemnifying Party. In the event of any such Proceeding (whether arising before or after the Effective Time), (i) the Indemnifying Party shall have the right to assume the defense thereof with counsel which is reasonably satisfactory to the Indemnified Party and the Indemnifying Party shall not be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if the Indemnifying Party elects not to assume such defense or counsel for the Indemnified Parties advises that there are issues which raise actual or potential conflicts of interest between the Indemnifying Party and the Indemnified Parties, the Indemnified Parties may retain counsel which is reasonably satisfactory to the Indemnifying Party, and the Indemnifying Party shall pay, promptly as statements therefor are received, the reasonable fees and expenses of such counsel for the Indemnified Parties (which may not exceed one firm in any jurisdiction unless counsel for the Indemnified Parties advises that there are issues that raise conflicts of interest between the Indemnified Parties), (ii) the Indemnified Parties will reasonably cooperate in the defense of any such matter, (iii) the Indemnifying Party shall not be liable for any settlement effected without its prior written consent and (iv) the Indemnifying Party shall have no obligation hereunder in the event that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable laws and regulations or by a final non-appealable adjudication of an applicable federal or state banking agency or a court of competent jurisdiction.

(c) Prior to the Effective Time, NBT shall purchase an extended reporting period endorsement under Evans’s existing directors’ and officers’ liability insurance coverage for Evans’s directors and officers in a form acceptable to Evans which shall provide such directors and officers with coverage for six years following the Effective Time for claims made against such directors and officers arising from any act, error or omission by such directors and officers existing or occurring at or prior to the Effective Time of not less than the existing

TABLE OF CONTENTS

coverage under, and have other terms at least as favorable to, the directors and officers than the directors’ and officers’ liability insurance coverage presently maintained by Evans (provided that NBT may substitute therefor policies which are not materially less advantageous than such policy or single premium tail coverage with policy limits equal to Evans’s existing coverage limits), so long as the aggregate cost is not more than 250% of the annual premium currently paid by Evans for such insurance (the “Premium Limit”). In the event that the Premium Limit is insufficient for such coverage, NBT shall use its reasonable best efforts to purchase such lesser coverage as may be obtained with such amount.

(d) The rights of indemnification and advancement as provided by this Section 5.13 shall not be deemed exclusive of any other rights to which the Indemnified Party may at any time be entitled under the Certificate of Incorporation, as amended, and the Amended and Restated Bylaws of Evans or as provided in applicable law as in effect on the date hereof (subject to change as required by law), any agreement, a vote of stockholders, a resolution of directors of Evans, or otherwise. In the event that an Indemnified Party, pursuant to this Section 5.13, seeks an adjudication of such person’s rights under, or to recover damages for breach of, this Section 5.13, or to recover under any directors’ and officers’ liability insurance coverage maintained by Evans or NBT, the Indemnifying Party shall pay on such Indemnified Party’s behalf, any and all reasonable costs, expenses and fees (including reasonable attorneys’ fees ) incurred by such Indemnified Party in such judicial adjudication, to the fullest extent permitted by law, only to the extent that the Indemnified Party prevails in such judicial adjudication.

(e) If NBT or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger, or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of NBT shall assume the obligations set forth in this Section 5.13.

Section 5.14 Employees; Benefit Plans.

(a) Following the Closing Date and except to the extent an alternative treatment is set forth in this Section 5.14, NBT may choose to maintain any or all of the Evans Benefit Plans in its sole discretion, and Evans and Evans Bank shall cooperate with NBT in order to effect any plan terminations to be made as of the Effective Time as set forth in this Section 5.14 and in accordance with the terms of the applicable Evans Benefit Plans and applicable law. For the period commencing at the Effective Time and ending twelve (12) months after the Effective Time (or until the applicable Continuing Employee’s earlier termination of employment), NBT shall provide, or cause to be provided, to each employee of Evans Bank who continues with the Surviving Bank as of the Closing Date (a “Continuing Employee”) (i) a base salary or a base rate of pay at least equal to the base salary or base rate of pay provided to similarly situated employees of NBT or any Subsidiary of NBT (or until the applicable Continuing Employee’s earlier termination of employment), and (ii) other benefits (other than severance or termination pay in order to avoid a duplication of benefits, if applicable) at least substantially comparable in the aggregate to the benefits provided to similarly situated employees of NBT or any Subsidiary of NBT. For any Evans Benefit Plan terminated for which there is a comparable NBT Benefit Plan of general applicability, NBT shall take all commercially reasonable action so that Continuing Employees shall be entitled to participate in such NBT Benefit Plan to the same extent as similarly-situated employees NBT (it being understood that inclusion of the employees of Evans and Evans Bank in the NBT Benefit Plans may occur at different times with respect to different plans). NBT shall cause each NBT Benefit Plan in which Continuing Employees are eligible to participate to take into account for purposes of eligibility and vesting under the NBT Benefit Plans (but not for purposes of benefit accrual) the service of such employees with Evans or Evans Bank to the same extent as such service was credited for such purpose by Evans or Evans Bank; provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits or retroactive application. Nothing herein shall limit the ability of NBT to amend or terminate any of the Evans Benefit Plans or NBT Benefit Plans in accordance with their terms at any time. Following the Closing Date, NBT shall honor, in accordance with Evans’s policies and procedures in effect as of the date hereof, any employee expense reimbursement obligations of Evans for out-of-pocket expenses incurred during the calendar year in which the Closing occurs by any Continuing Employee and all accrued but unused vacation credited to any Continuing Employee under Evans Benefit Plans.

(b) Without limiting the generality of Section 5.14(a), prior to the Closing Date, (i) Evans or Evans Bank, as applicable, shall take all actions necessary to terminate the Evans Bancorp, Inc. Executive Severance Plan and Evans Bank Change in Control Severance Plan (together, the “Evans Bank Severance Plan”), and to adopt

A-38

TABLE OF CONTENTS

written resolutions, the form and substance of which shall be reasonably satisfactory to NBT, to terminate such Evans Bank Severance Plan, and (ii) if requested by NBT in writing not less than forty-five (45) days prior to the Closing Date, Evans or Evans Bank, as applicable, shall take all actions necessary to cease contributions to and terminate each Evans Benefit Plan that is intended to qualify under Code Section 401(k) (each, a “Evans 401(k) Plan”), and to adopt written resolutions, the form and substance of which shall be reasonably satisfactory to NBT, to terminate such Evans 401(k) Plan; provided, however, that such termination may be made contingent upon the consummation of the transactions contemplated by this Agreement. In such event, NBT shall take any and all actions as may be required to permit Continuing Employees to participate in a NBT Benefit Plan that is intended to qualify under Code Section 401(k) (an “NBT 401(k) Plan”) immediately following the Closing Date and to permit Continuing Employees to roll over their account balances in the Evans 401(k) Plan, including any participant loans under the Evans 401(k) Plan, into the NBT 401(k) Plan. If requested by NBT in writing at any time following the date of this Agreement, Evans or Evans Bank, as applicable, shall initiate the process to terminate its tax-qualified defined benefit pension plan, with such termination effective as soon as practicable after the Effective Time, and Evans shall keep NBT informed regarding the progress and status of the termination process.

(c) If employees of Evans or Evans Bank become eligible to participate in a medical, dental, vision, prescription drug, disability plan or life insurance plan of NBT upon termination of such plan of Evans or Evans Bank, NBT shall use all commercially reasonable efforts to cause each such plan to (i) waive any preexisting condition limitations to the extent such conditions are covered under the applicable NBT Benefit Plan, (ii) provide credit under such plans for any deductible, co-payment and out-of-pocket expenses incurred by the employees and their beneficiaries during the portion of the calendar year prior to such participation and (iii) waive any waiting period limitation, actively-at-work requirement or evidence of insurability requirement which would otherwise be applicable to such employee on or after the Effective Time, in each case to the extent such employee had satisfied any similar limitation or requirement under an analogous Evans Benefit Plan prior to the Effective Time; provided, however, NBT shall not cause any coverage of a Continuing Employee or such Continuing Employee’s dependents to terminate under any Evans Benefit Plan which is a health or welfare plan prior to the time such Continuing Employees or such Continuing Employee’s dependents, as applicable, have been offered participation in the health and welfare plans common to all employees of NBT and their dependents, except in the case of a termination of employment or other service.

(d) From and after the Effective Time, NBT agrees to honor all obligations under the employment agreements, change in control agreements, supplemental executive retirement plans, and similar arrangements as set forth on Evans Disclosure Schedule 5.14(d). NBT shall assume and honor all Evans Benefit Plans listed on Evans Disclosure Schedule 5.14(d) in accordance with their terms. Evans Disclosure Schedule 5.14(d) sets forth the names of all participants, the value of each participant’s account balance and the amount of each lump sum or installment payment under the applicable non-qualified deferred compensation plan.

(e) NBT agrees to pay to each employee of Evans or Evans Bank that is not covered by a written employment or severance agreement and is terminated by NBT or any of its Subsidiaries, without cause, within six (6) months following the Effective Time, a severance payment equal to two (2) weeks of his or her then current base salary multiplied by the number of total completed years of service with Evans or Evans Bank; provided, however, that for vice presidents and above, severance payment shall equal twenty-six (26) weeks of his or her base salary and for all other employees, the minimum severance payment shall equal not less than twelve (12) weeks of his or her base salary and the maximum severance payment shall not exceed twenty-six (26) weeks of his or her base salary; and provided further, that such employee enters into a release of claims in a form reasonably satisfactory to NBT and that such employee does not voluntarily leave employment with Evans or Evans Bank prior to the Effective Time.

(f) To the extent necessary, NBT and Evans may provide a retention pool as mutually agreed by NBT and Evans to enable NBT and Evans to provide retention incentives to certain employees of Evans or Evans Bank who are not covered by a written employment agreement, the recipients and amounts to be mutually determined by NBT and Evans. Such retention incentives will be in addition to, and not in lieu of, any severance payment, including the amount that may be paid pursuant to Section 5.14(e). Such designated employees will enter into retention agreements to be provided by Evans and reasonably acceptable to NBT.

(g) Notwithstanding anything in this Agreement to the contrary, NBT shall honor and agree to not terminate the Evans Benefit Plans set forth on Evans Disclosure Schedule 5.14(g) and the parties agree that the

A-39

benefits under such Evans Benefit Plans shall be paid out in accordance with the terms and conditions of such Evans Benefit Plans; provided, however, that Evans or Evans Bank, as applicable, shall take all actions necessary to cease all participant contributions to all such plans following the Closing Date, subject to compliance with Section 409A of the Code, the terms and conditions of such plans and applicable law.

(h) Nothing contained in this Agreement, expressed or implied, shall (i) give any person, other than the parties hereto, any rights or remedies of any nature whatsoever, including any right to continued employment or service, under or by reason of this Section 5.14, (ii) cause any third party beneficiary rights in any current or former employee, director, other individual service provider of Evans or any of its Subsidiaries to enforce the provisions of this Section 5.14 or any other matter related thereto, or (iii) be construed as an amendment to any Evans Benefit Plan, NBT Benefit Plan, or other employee benefit plan of NBT, NBT Bank, Evans or any of their respective Affiliates, or be construed to prohibit the amendment or termination of any such plan.

(i) If requested by NBT, Evans shall take all such actions as NBT may request in order to fully and timely comply with any and all requirements of the WARN Act, including providing notices to employees of Evans or any Subsidiary of Evans.

Section 5.15 Notification of Certain Changes. Each of NBT and Evans shall promptly advise the other party of any change or event having, or which could be reasonably expected to have, a Material Adverse Effect on it or which it believes would, or which could reasonably be expected to, cause or constitute a material breach of any of its representations, warranties or covenants contained herein. From time to time prior to the Effective Time, but no more frequently than monthly (and no later than the date prior to the Closing Date), each party will supplement or amend its Disclosure Schedules delivered in connection with the execution of this Agreement to reflect any matter which, if existing, occurring or known at the date of this Agreement, would have been required to be set forth or described in such Disclosure Schedules or which is necessary to correct any information in such Disclosure Schedules which has been rendered inaccurate thereby. No supplement or amendment to such Disclosure Schedules shall have any effect for the purpose of determining the accuracy of the representations and warranties of the parties contained in Article III and Article IV in order to determine the fulfillment of the conditions set forth in Section 6.02(a) or Section 6.03(a) hereof, as the case may be, or the compliance by Evans or NBT, as the case may be, with the respective covenants and agreements of such parties contained herein.

Section 5.16 Current Information. During the period from the date of this Agreement to the Effective Time, Evans will cause one or more of its designated representatives to confer on a regular and frequent basis with representatives of NBT and to report the general status of the ongoing operations of Evans. Without limiting the foregoing, Evans agrees to provide NBT a copy of each report filed by Evans with a Governmental Authority within one (1) Business Day following the filing thereof.

Section 5.17 Board Packages. Evans shall distribute a copy of each Evans Board package, including the agenda and any draft minutes, to NBT at the same time and in the same manner in which it distributes a copy of such packages to the Evans Board; provided, however, that Evans shall not be required to copy NBT on any documents that disclose confidential discussions of this Agreement or the transactions contemplated hereby or any third party proposal to acquire control of Evans or any other matter that the Evans Board has been advised of by counsel that such distribution to NBT may violate a confidentiality obligation, any material legal privilege or fiduciary duty or any law or regulation.

Section 5.18 Transition; Informational Systems Conversion. From and after the date hereof, NBT and Evans shall each use their reasonable best efforts to facilitate the integration of Evans with the business of NBT following consummation of the transactions contemplated by this Agreement, and shall meet on a regular basis to discuss and plan for the conversion of Evans’s data processing and related electronic informational systems (the “Informational Systems Conversion”) to those used by NBT and its Subsidiaries, which planning shall include, but not be limited to: (a) discussion of Evans’s third-party service provider arrangements; (b) non-renewal of personal property leases and software licenses used by Evans in connection with its systems operations; (c) retention of outside consultants and additional employees to assist with the conversion; (d) outsourcing, as appropriate, of proprietary or self-provided system services; and (e) any other actions necessary and appropriate to facilitate the conversion, as soon as practicable following the Effective Time. If this Agreement is terminated by NBT and/or Evans in accordance with Section 7.01(a), Section 7.01(c), or Section 7.01(f), or by Evans only

A-40

in accordance with Section 7.01(d) or Section 7.01(e), NBT shall pay to Evans all reasonable fees, expenses or charges related to reversing the Informational Systems Conversion within ten (10) Business Days of Evans providing NBT written evidence of such fees, expenses or charges.

NBT agrees to execute and deliver, or cause to be executed and delivered, by or on behalf of the Surviving Corporation, at or prior to the Effective Time, one or more supplemental indentures, guarantees, and other instruments required for the due assumption of the Evans’s outstanding debt, guarantees, securities, and other agreements to the extent required by the terms of such debt, guarantees, securities, and other agreements.

Prior to the Effective Time, each of the Evans Board and the NBT Board, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall take all such reasonable action as may be required to cause to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act, to the fullest extent permitted by applicable law, any acquisitions or dispositions of shares of Evans Stock and NBT Stock (including derivative securities with respect to such shares) that are treated as acquisitions or dispositions under such rule and result from the transactions contemplated by this Agreement by officers and directors of Evans subject to the reporting requirements of Section 16(a) of the Exchange Act or by each individual who is reasonably expected to become subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to NBT immediately after the Effective Time.

Promptly following the Effective Time, NBT Bank shall invite the directors of Evans who are members of the Evans Board immediately prior to the Effective Time, other than the New Board Member, to join a Western New York and Finger Lakes Region Advisory Board of NBT Bank; provided that any director of Evans invited to join the Western New York and Finger Lakes Region Advisory Board must meet the applicable qualifications of such advisory board in order to join.

Ladies and Gentlemen:

Evans Bancorp, Inc. (“Evans”), Evans Bank, National Association (the “Evans Bank”), NBT Bancorp Inc. (“NBT”) and NBT Bank, National Association (“NBT Bank”) are proposing to enter into an Agreement and Plan of Merger (the “Agreement”) pursuant to which Evans will, subject to the terms and conditions set forth therein, merge with and into NBT (the “Merger”) so that NBT is the surviving corporation in the Merger. As set forth in the Agreement, at the Effective Time, each share of Evans Stock issued and outstanding immediately prior to the Effective Time, except for certain shares of Evans Stock as specified in the Agreement, shall become and be converted into the right to receive 0.91 (the “Exchange Ratio”) of a share of NBT Stock. Capitalized terms used herein without definition shall have the meanings ascribed thereto in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Exchange Ratio to the holders of Evans Stock.

Piper Sandler & Co. (“Piper Sandler”, “we” or “our”), as part of its investment banking business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed and considered, among other things: (i) a draft of the Agreement, dated September 3, 2024; (ii) certain publicly available financial statements and other historical financial information of Evans and Evans Bank that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of NBT and NBT Bank that we deemed relevant; (iv) publicly available analyst consensus earnings per share estimates for Evans for the years ending December 31, 2024 and December 31, 2025 as well as an estimated long-term annual earnings per share growth rate for the years thereafter and estimated dividends per share for Evans for the years ending December 31, 2024 through December 31, 2028, as provided by the senior management of Evans; (v) internal financial projections for NBT for the year ending December 31, 2024 with a long-term annual balance sheet and net income growth rate for the years ending December 31, 2025 through December 31, 2028 and estimated dividends per share for NBT for the years ending December 31, 2024 through December 31, 2028, as provided by the senior management of NBT; (vi) the pro forma financial impact of the Merger on NBT based on certain assumptions relating to transaction expenses, cost savings and purchase accounting adjustments, as well as estimated net income for each of Evans and NBT for the year ending December 31, 2024 with an estimated long-term earnings growth rate for the years thereafter, as provided by the senior management of NBT; (vii) the publicly reported historical price and trading activity for Evans Stock and NBT Stock, including a comparison of certain stock trading information for Evans Stock and NBT Stock and certain stock indices, as well as similar publicly available information for certain other companies, the securities of which are publicly traded; (viii) a comparison of certain financial and market information for Evans and NBT with similar financial institutions for which information is publicly available; (ix) the financial terms of certain recent business combinations in the bank and thrift industry (on nationwide basis), to the extent publicly available; (x) the current market environment generally and the banking environment in particular; and (xi) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of the senior management of Evans and its representatives the business, financial condition, results of operations and prospects of Evans and held similar discussions with certain members of the senior management of NBT and its representatives regarding the business, financial condition, results of operations and prospects of NBT.

respective representatives, or that was otherwise reviewed by us and we have assumed such accuracy and completeness for purposes of rendering this opinion without any independent verification or investigation. We have further relied on the assurances of the respective senior managements of Evans and NBT that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading in any respect material to our analyses. We have not been asked to undertake, and have not undertaken, an independent verification of any such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Evans or NBT, nor were we furnished with any such evaluations or appraisals. We render no opinion on or evaluation of the collectability of any assets or the future performance of any loans of Evans or NBT, nor any of their respective subsidiaries. We did not make an independent evaluation of the adequacy of the allowance for loan losses of Evans or NBT, any of their respective subsidiaries or the combined entity after the Merger, and we have not reviewed any individual credit files relating to Evans or NBT or any of their respective subsidiaries. We have assumed, with your consent, that the respective allowances for credit losses for Evans and NBT and their respective subsidiaries are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used publicly available analyst consensus earnings per share estimates for Evans for the years ending December 31, 2024 and December 31, 2025 as well as an estimated long-term annual earnings per share growth rate for the years thereafter and estimated dividends per share for Evans for the years ending December 31, 2024 through December 31, 2028, as provided by the senior management of Evans. In addition, Piper Sandler used internal financial projections for NBT for the year ending December 31, 2024 with a long-term annual balance sheet and net income growth rate for the years ending December 31, 2025 through December 31, 2028 and estimated dividends per share for NBT for the years ending December 31, 2024 through December 31, 2028, as provided by the senior management of NBT. Piper Sandler also received and used in its pro forma analyses certain assumptions relating to transaction expenses, cost savings and purchase accounting adjustments, as well as estimated net income for each of Evans and NBT for the year ending December 31, 2024 with an estimated long-term earnings growth rate for the years thereafter, as provided by the senior management of NBT. With respect to the foregoing information, the respective senior managements of Evans and NBT confirmed to us that such information reflected (or in the case of the publicly available analyst estimates referred to above, was consistent with) the best currently available projections, estimates and judgements of those respective senior managements as to the future financial performance of Evans and NBT, respectively, and we assumed that the financial results reflected in such information would be achieved. We express no opinion as to such projections, estimates or judgements, or the assumptions on which they are based. We have also assumed that there has been no material change in Evans’s or NBT’s assets, financial condition, results of operations, business or prospects since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analyses that Evans and NBT will remain as going concerns for all periods relevant to our analyses.

We have also assumed, with your consent, that (i) each of the parties to the Agreement will comply in all material respects with all material terms and conditions of the Agreement and all related agreements required to effect the Merger, that all of the representations and warranties contained in such agreements are true and correct in all material respects, that each of the parties to such agreements will perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements are not and will not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Evans, NBT, the Merger or any related transactions, and (iii) the Merger and any related transactions will be consummated in accordance with the terms of the Agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with your consent, we have relied upon the advice that Evans has received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Merger and the other transactions contemplated by the Agreement. We express no opinion as to any such matters.

Our opinion is necessarily based on financial, regulatory, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof could

materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof. We express no opinion as to the trading value of Evans Stock or NBT Stock at any time or what the value of NBT Stock will be once the shares are actually received by the holders of Evans Stock.

We have acted as Evans’s financial advisor in connection with the Merger and will receive a fee for our services, which fee is contingent upon consummation of the Merger. We will also receive a fee for rendering this opinion, which opinion fee will be credited in full towards the advisory fee which will become payable to Piper Sandler upon consummation of the Merger. Evans has also agreed to indemnify us against certain claims and liabilities arising out of our engagement and to reimburse us for certain of our out-of-pocket expenses incurred in connection with our engagement. In the two years preceding the date hereof, Piper Sandler provided other investment banking services to Evans. In summary, Piper Sandler acted as financial advisor to Evans in connection with the sale of its subsidiary, The Evans Agency, LLC, which transaction closed in November 2023 and for which Piper Sandler received approximately $2.3 million in advisory fees. As you are aware, Piper Sandler provided certain investment banking services to NBT in the two years preceding the date hereof. In summary, Piper Sandler rendered an opinion to the Board of Directors of NBT in connection with NBT’s acquisition of Salisbury Bancorp, Inc. in December 2022 for which Piper Sandler received a fee of $500,000. In addition, in the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to Evans, NBT and their respective affiliates. We may also actively trade the equity and debt securities of Evans, NBT and their respective affiliates for our own account and for the accounts of our customers.

Our opinion is directed to the Board of Directors of Evans in connection with its consideration of the Agreement and the Merger and does not constitute a recommendation to any shareholder of Evans as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the Agreement and the Merger. Our opinion is directed only as to the fairness, from a financial point of view, of the Exchange Ratio to the holders of Evans Stock and does not address the underlying business decision of Evans to engage in the Merger, the form or structure of the Merger or any other transactions contemplated in the Agreement, the relative merits of the Merger as compared to any other alternative transactions or business strategies that might exist for Evans or the effect of any other transaction in which Evans might engage. We also do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Merger by any Evans officer, director or employee, or class of such persons, if any, relative to the amount of compensation to be received by any other shareholder. This opinion has been approved by Piper Sandler’s fairness opinion committee. This opinion may not be reproduced without Piper Sandler’s prior written consent; provided, however, Piper Sandler will provide its consent for the opinion to be included in any regulatory filings, including the Prospectus/Proxy Statement and the Merger Registration Statement, to be filed with the SEC and mailed to shareholders in connection with the Merger.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio is fair to the holders of Evans Stock from a financial point of view.
